Fig. 12.1 "Tools >..." Menubar - Tools Overview

This chapter describes the various Tools available in Gramps.

Gramps Tools allow you to perform various types of analysis of your genealogical data. Typically, the tools do not produce output in form of printouts or files. Instead, they produce screen output immediately available for the researcher. However, when appropriate, you can save the results of running a tool into a file.

Tools

Fig. 12.2 Toolbar Icon for "Open the tools dialog"

The tools can be accessed by choosing the menu Tools ->Tool Section ->Particular Tool .

Alternatively, you can browse the complete selection of available tools along with their brief descriptions in a Tool Selection dialog invoked by clicking the Open the tools dialog icon on the toolbar from any of the categories.

The Tool Selection dialog allows you to browse the complete selection of available tools along with their brief descriptions when invoked by clicking the Open the tools dialog icon on the toolbar from any of the categories.

Analysis and Exploration

This section contains tools which analyze and explore the database, but do not alter it. The following analysis and exploration tools are currently available in Gramps:

Compare Individual Events

Fig. 12.4 "Compare Individual Events" - "Event comparison filter selection" - dialog

This tool compares events across the selected group of people.

You can use this tool via menu Tools->Analysis and Exploration > Compare Individual Events... which will open the Event comparison filter selection dialog

The people for this comparison can be chosen from previously created custom filters by selecting the Filter: drop down list, which defaults to the Entire Database. Or by selecting the Custom Filter Editor button, to create custom filters in the Person Filters editor. To run the report select Apply and the results will be displayed in the Event Comparison Results dialog.


From the Event Comparison Results dialog you can view the results or Save as the resulting table as a spreadsheet (ODS format). Select Close to exit the report.

Family Tree Processing

This section contains tools which may modify your database. The tools from this section are used mostly for finding and correcting errors in the data. The following Family Tree Processing tools are currently available in Gramps:

Gramps-notes.png
Note

The modifications will only be performed upon your explicit consent, except for the automatic fixes performed by Check and repair Database tool.

Edit Database Owner Information

Fig. 12.6 "Database Owner Editor" - dialog - showing context menu

This tool modifies any existing Researcher Information.

Select the menu Tools->Family Tree Processing->Edit Database Owner Information.... This brings up the Database Owner Editor window, where you can fill in the needed info.

  • Name:
  • Street:
  • Locality:
  • City:
  • State/County:
  • Country:
  • ZIP/Postal Code:
  • Phone:
  • Email:

This information is family tree specific and will be used when exporting your data in GEDCOM format.

Two choices are available from the context menu(right click):

  • Copy from DB to Preferences -
  • Copy from Preferences to DB -


Extract Event Description

Gramps-notes.png
Note

The name format in the Event's Description field depends on the defined name format in Edit->Preferences->Display->Name format

Fig. 12.7 Extract Event Description's - Modifications Made - window - example result

Extracts event descriptions from the event data by using a model :

{event type} of {Surname}, {Given name}

If event description is missing, then tool will use this event description field model.

You can access this tool via the menu Tools->Family Tree Processing->Extract Event Description...

The Undo history warning will be shown and you can either Stop or Proceed with the tool.

Once you Proceed with the tool this tool will scan and modify your Family Tree and present you with the Modifications made result window listing the total number of event descriptions that have been added.

Extract Information from Names

This tool searches the entire database and attempts to extract titles and nicknames that may be embedded in a person's Given name field. If any information could be extracted, the candidates for fixing will be presented in the table. You may then decide which to repair as suggested and which not to.

You can access this tool via the menu Tools->Family Tree Processing->Extract Information from Names....

The Undo history warning dialog will be shown and you can either Stop or Proceed with the tool.

Fig. 12.8 "Default prefix and connector settings" - dialog for the "Extract Information from Names" Tool

The Default prefix and connector settings dialog will be shown and you can modify each of the options as required:

  • Prefixes to search for: de, van, von, di, le, du, dela, della, des, vande, ten, da, af, den, das, dello, del, en, ein, elet, les, lo, los, un, um, una, uno, der, ter, te, die (default)
  • Connectors splitting surnames: e, y (default)
  • Connectors not splitting surnames: de, van (default)

Once you have finished select OK to start the tool.

No longer part of Gramps you can download this tool from the third party addons
See: Extract Place Data from a Place Title

Find Possible Duplicate People

Fig. 12.10 Find Possible Duplicate People - dialog - default

This tool searches the entire database, looking for the entries that may represent the same person.

You can access this tool via the menu Tool->Family Tree Processing->Find Possible Duplicate People....

The Find Possible Duplicate People dialog will be shown and you can adjust the following options:

  • Match Threshold : choose between Low(default), Medium and High from the drop down menu. (Note:This calculates a chance of matching as a floating point number. For each piece of information that matches the chance is increased. If the chance is greater than the threshold then a match is reported. The thresholds are Low=0.25, Medium=1.0 and High=2.0. So with the threshold set to High less matches are expected.)

Options

  • Use soundex codes for matching possible duplicate people. (checkbox checked by default)

The following buttons are present: Help brings you to this page, Cancel to stop processing and an OK button to start processing the data.

Select OK to start the tool and the data will be processed in two passes.

  • Pass 1: Building preliminary lists
  • Pass 2: Calculating potential matches.

A progress bar will be shown and depending the speed of your computer and the amount of people in the database this can take some time.


Fig. 12.11 "Potential Merges" result dialog window for "Find Possible Duplicate People" - dialog - example

Once the report finishes a Potential Merges result list window is presented with the following columns shown:

  • Rating : this gives you an idea of the resemblance between the two people. The higher the ranking, the higher the chance that the people are duplicates.
  • First Person
  • Second Person

You can either double-click on the selected row or select the Compare button to check the details.

Three buttons are present: Help brings you to this page, a Close to close the window which returns you to the Find Possible Duplicate People window and a Compare button to which brings up the Merge People window which was explained in detail in the Merge People Dialog. Here you can select with the radio buttons one of the persons and eventually use the OK button to merge the data if you find the two persons are duplicates.

Selecting the Cancel button brings you back to the Potential Merges result list window.

Fix Capitalization of Family Names

This tool searches the entire database and attempts to fix the capitalization of family names.

The aim is to have conventional capitalization: capital first letter and lower case for the rest of the family name. If deviations from this rule are detected, the candidates for fixing will be presented in the table.

You may then decide which to repair as suggested and which not to.

You can use this tool via menu Tools->Family Tree Processing->Fix Capitalization of Family Names....

Gnome-important.png
Undo history

Proceeding with this tool will erase the undo history for this session. In particular, you will not be able to revert the changes made by this tool or any changes made prior to it. It is recommended that you please stop here and backup your database; so that you can revert the process of running this tool.

The Undo history warning will be shown and you can either Stop or Proceed with the tool.


Fig. 12.12 "Capitalization changes" - dialog - results example for "Fix Capitalization of Family Names" tool

If there where changes to the capitalization of any names you will be presented with the Capitalization changes results window. The window shows a list of the family names that Gramps can convert to (according to Gramps) correct capitalization (please check that it is correct for you.). In the Capitalization changes results window list the following columns are available:

  • Select - Check or uncheck these on a by name bases if you choose not to accept the recommendation (checkbox checked by default)
  • Original Name - The name as currently recorded.
  • Capitalization Change - The name with change if applied.

Select the names you want to be changed, then select the Accept changes and close button. Or use the Cancel button to abort changes.

You can also install the "Fix Capitalization of Given Names" tool Addon that once installed works almost identically to this tool but works for "Given Names"

Merge citations

The Merge Citations tool

works by combining notes, media objects and data-items of matching citations.


You can select this via menu Tools > Family Tree Processing > Merge Citations... .

The Undo history warning will be shown and you can either Stop or Proceed with the tool.

Fig. 12.13 "Merge Citations" - dialog - default

Then the Merge Citations dialog (Title of dialog shows:Notes, media objects and data-items of matching citations will be combined.)will be shown

The following options are available:

  • Match Threshold drop down list:
    • Match on Page/Volume, Date and Confidence
    • Ignore Date (default)
    • Ignore Confidence
    • Ignore Date and Confidence
  • Options
    • Don't merge if citation has notes (checkbox unchecked by default)


Fig. 12.14 "Number of merges done" result dialog for "Merge Citations" - dialog - Tool - example

Select OK to run the tool and once complete it will report back the total with the Number of merges done result dialog.
See also the Merge Citations option available from the Citations Category list view

Rename Event Types

This tool will rename all events of one type to a different type.

You can access this tool via the menu Tools->Family Tree Processing->Rename Event Types....

The Undo history warning will be shown and you can either Stop or Proceed with the tool.

Undo history

Proceeding with this tool will erase the undo history for this session. In particular, you will not be able to revert the changes made by this tool or any changes made prior to it. If you think you may want to revert running this tool, please stop here and backup your database.


Fig. 12.15 "Change Event Types" - dialog - example for "Rename Event Types" Tool

The Change Event Types dialog is presented.

  • Original event type: fill in the text field or use the drop down menu and select an original event type
  • New event type: fill in the text field (you can create a complete new type here) or use the drop down menu and select a new type

The example shows a renaming of the Birth event to a Baptism event.

Gramps-notes.png
Custom types

While the custom types do not show in the drop down list, you can over type or paste into either of the selection boxes and convert from one to another.



Fig. 12.16 "Change types" - result dialog - example for "Rename Event Types" Tool

Finally use the Cancel to exit or select OK to run the tool and once complete it will report back the total events modified with the Change types result dialog.

Reorder Gramps ID

This tool can be used to Reorder your Gramps IDs. Several options are available.

Gnome-important.png
Custom IDs'

If you customized your IDs', all those can be replaced by this tool. So take care before you use this tool!

Fig. 12.17 Reorder IDs

You can use this tool via menu Tools->Family Tree Processing->Reorder Gramps IDs....

The 'Object' column lists the type of ID. Immediately to the left of this column are checkboxes that allow the enabling of changes to individual object types. When checked, the type can be reordered. The 'Object' label is actually a button that can be used to toggle all of the check boxes at once.

The 'Actual' column shows an example of the current ID. The 'Quantity' column show the number of objects.

The 'Format' column can be used to change the ID format for each object type. Note that the format consists of a prefix, the '%04d' and suffix. There MUST be at least a prefix or a suffix, both are allowed. It is recommended to keep these relatively short. The '%04d' defines the length of the numeric portion of the ID, the '4' can be changed, anything from '3' (allowing numbers from 000-999) to '9' (000000000-999999999) is allowed. Changes made here are the same as made in the menu Edit->Preferences... and then select the ID Formats tab. The 'Format' label is actually a button that can be used to reset all the formats to the last used value.

The 'Change' column contains checkboxes for each object type. If this is checked, the IDs for that object will be replaced with new IDs of the 'Format' style, unless 'Keep' is also checked. If there is no check, the ID formats are NOT updated, but the number field within the format is renumbered. The 'Change' label is actually a button that can be used to toggle all of the check boxes at once.

The 'Start' field indicates the starting number used during the renumber operation. The 'Start' label is actually a button that can be used to toggle between start at 0, and start after last current number.

The 'Step' field indicates the interval between numbers during the renumber, '1' is a simple increment, '2' will increment by 2 etc. The 'Step' label is actually a button that can be used to toggle between '1', '2', '5', and '10'.

The 'Keep' column contains checkboxes for each object type. If this and 'Change' is checked, the ID formats for that object will be retained, and the number field within the format is renumbered. The 'Keep' label is actually a button that can be used to toggle all of the check boxes at once.

The Undo history warning will be shown and you can either Stop or Proceed with the tool.

Gnome-important.png
Undo history

Proceeding with this tool will erase the undo history for this session. In particular, you will not be able to revert the changes made by this tool or any changes made prior to it. If you think you may want to revert running this tool, please stop here and backup your database.

When you click 'OK', the tool will show a progress bar.

In different stages the following IDs' are reordered: Reordering People IDs', Reordering Family IDs', Reordering Event IDs', Reordering Media Object IDs', Reordering Source IDs', Reordering Citation IDs', Reordering Place IDs', Reordering Repository IDs' and finally Reordering Note IDs'.

In a next step unused IDs' are searched for and assigned.

During this process the tool will examine each ID to see if it looks like it has been 'customized', if it doesn't look like the previous ID format or the default ID format. This might be the case if the user had entered his own text in the ID field for the object when editing it. It might also occur if the third party GetGOV Addon or GeoName Addon has been used, as that tool stores the GOV ID in the ID field. If a 'customized' ID is found, it will ask the user if he really wants to replace the ID. The dialog also allows the user to use the same answer for other customized IDs found.

Sort Events

Events appearing on the Event tab on a Person or Family Editor are not sorted in any particular order other than the order that the events were added. The reason for not enforcing any particular ordering, particularly ordering by date, is to allow for the situation where an event was known to have happened but the exact chronology is not. Importing or merging data from an external source can lead to extra events being added to, but out of sequence with, the existing set of events of a person or family.

Events can be manually re-ordered by drag & drop or by use of the re-order buttons on the Events tab. Either way, an event can be moved up or down in the list of events and Gramps will remember the new order when the changes are saved. The new ordering will be used wherever events are shown elsewhere in Gramps, such as on a report.

The order of all events on a tab can also be changed by clicking a column title. For example, clicking the 'Date' column header will sort all the events in date order. However this way of sorting events is temporary and changes to the event order are not preserved when the window is closed.

The drag and drop approach to sorting events is fine for moving a small number of events but is not practical for large scale changes. The Sort Events tool has been designed specifically for this purpose, re-sorting all events in the database or just those associated with a targeted selection of people chosen by using a filter.

You can use this tool via menu Tools->Family Tree Processing->Sort events....

The Undo history warning will be shown and you can either Stop or Proceed with the tool.

Gnome-important.png
Undo history

Proceeding with this tool will erase the undo history for this session. In particular, you will not be able to revert the changes made by this tool or any changes made prior to it. If you think you may want to revert running this tool, please stop here and backup your database.


Fig. 12.18 "Sort Events" - dialog - showing "Tool Options" tab for "Sort Events" Tool

The first option on the Sort Events dialog window is used to define the range of people who's events are to be sorted. The first choice in the list is to apply the sorting to all people in the database. Alternative choices are to apply sorting to ancestors and descendants of a chosen person or to a range of people selected by a custom built person filter. After choosing who the sort should apply to, the next thing to consider is how the events should be sorted. The first option is to sort by date. This is probably the most likely choice, but other event attributes can be chosen too. The final choices are whether to make the events sorted ascending or descending and whether to apply the sort to family events that the selected people belong to as well.

Sorting events

Once completed, this cannot be undone by the regular Undo function.

Family Tree Repair

Check and Repair Database

Gnome-important.png
Warning

The Check and repair Database tool performs automatic fixes. Once completed, this cannot be undone by the regular Undo function.

This tool checks the database for integrity problems, fixing the problems it can. Specifically, the tool is checking for:

  • Broken family links. These are the cases when a person's record refers to a family while the family's record does not refer to that person, and vice versa.
  • Missing media objects. The missing media object is the object whose file is referenced in the database but does not exist. This can happen when the file is accidentally deleted, renamed, or moved to another location.
  • Empty families. These are the family entries which have no reference to any person as their member.
  • Parent relationship. This checks all families to ensure that father and mother are not mixed up. The check is also made that parents have different gender. If they have common gender then their relationship is renamed to "Partners".

You can use this tool via menu Tools->Family Tree Repair->Check and Repair Database....

Gnome-important.png
Undo history

Proceeding with this tool will erase the undo history for this session. In particular, you will not be able to revert the changes made by this tool or any changes made prior to it. It is recommended that you please stop here and backup your database; so that you can revert the process of running this tool.

The Undo history warning will be shown and you can either Stop or Proceed with the tool.


Fig. 12.19 "Integrity Check Results" - example result dialog - for the "Check and Repair Database" tool

Any issues found are automatically fixed and the Integrity Check Results dialog will be shown with a summary actions taken.
Otherwise you will see the No errors were found dialog stating that The database has passed internal checks.

Rebuild Gender Statistics

Fig. 12.20 "Gender statistics rebuilt" - result dialog for "Rebuild Gender Statistics" tool

Rebuilds gender statistics for name gender guessing...

You can use this tool via menu Tools->Family Tree Repair->Rebuild Gender Statistics....

Once completed the Gender statistics rebuilt result dialog will be shown.

Rebuild Reference Maps

Fig. 12.21 "Reference maps rebuilt" - result dialog for "Rebuild Reference Maps" tool

This tool rebuilds reference map tables (References items on editors).

You can use this tool via menu Tools->Family Tree Repair->Rebuild Reference Maps....

Once completed the Reference maps rebuilt result dialog will be shown.

Rebuild Secondary Indexes

Fig. 12.22 "Secondary indexes rebuilt" - result dialog for "Rebuild Secondary Indexes" tool

This tool rebuilds secondary indices.

You can use this tool via menu Tools->Family Tree Repair->Rebuild Secondary Indexes....

Once completed the Secondary indexes rebuilt result dialog will be shown.

Remove Unused Objects

This tool will search your database for pieces of information which are not connected to anything else, and then allow you to edit and attach the information or remove them.

You can use this tool via menu Tools->Family Tree Repair->Remove Unused Objects....


Fig. 12.23 "Unused Objects" - dialog example results for "Remove Unused Objects" tool

The Unused Objects dialog is presented.

You can choose from the search option you want to use from the top section of the Unused Objects dialog:

  • Search for events (checkbox checked by default)
  • Search for sources (checkbox checked by default)
  • Search for citations (checkbox checked by default)
  • Search for places (checkbox checked by default)
  • Search for media (checkbox checked by default)
  • Search for repositories (checkbox checked by default)
  • Search for notes (checkbox checked by default)

Select the Find button to run the report, and once completed the results if any will show in the bottom section of the Unused Objects dialog with the following columns shown:

  • Mark Select the row if you want to delete the object (checkbox unchecked by default)
  • - Icon representing the type of object.
  • ID - Gramps internal name for the object.
  • Name - of the object.

To examine the object you must double-click on the row and it will show the appropriate editor for the object allowing you to edit if required.

Mark the objects you want to delete either using the individual checkboxes or using the associated buttons:

  • Mark all
  • Unmark all
  • Invert marks

Once your deletion choices have been made select the Delete button to delete the objects.

When finished you may then use the Close button to exit the tool.

Utilities

This section contains tools allowing you to perform a simple operation on a portion of data. The results can be saved in your database, but they will not modify your existing data. The following utilities are currently available in Gramps:

Find database loop

Fig. 12.24 Find possible loop

The Find database loop utility allows you to verify if you have ancestral loops in the database.

Select this via the menu Tools->Utilities->Find database loop... you will get a Find database loop window. The window has five tabs; Gramps_ID,Parent, Gramps_ID, Child, Family ID.

  1. First Gramps_ID is a reference to the Parent.
  2. Parent (Ancestor on the image) is the person we are looking for a loop.
  3. Second Gramps_ID is a reference to the Child.
  4. Child (Descendant) is the origin of the loop.
  5. Family_ID is a reference to the associated family


Fig. 12.25 Find possible loop in a complex example

In the following complex example, we have multiple ancestral loops :

If we look at the second line, we have :

  1. First Gramps_ID : I0002
  2. Parent is : Father, Child2
  3. Second Gramps_ID : I0001
  4. Child is : Father, Father
  5. Family_ID is : F0000

To understand what happens :

  1. we start at [I0002] Father, Child2.
  2. We continue with his son [I0003] Father, Child3.
  3. We continue with his son : [I0000] Child, Child.
  4. We continue with his son : [I0001] Father, Father.
  5. We continue with his son : [I0002] Father, Child2 ==> HERE, we have a ancestral loop.

This article's content is incomplete or a placeholder stub.
Please update or expand this section.


Fig. 12.26 Introduction - page for "Gramps Media Manager" - Tool wizard

The Gramps Media Manager is a group of four separate tools accessed via a wizard like dialog that you can access via the menu Tools->Utilities->Media Manager... which will show the first Introduction dialog page with the following information on the tools abilities.

Gramps-notes.png
Introduction

This tool allows batch operations on media objects stored in Gramps. An important distinction must be made between a Gramps media object and its file.

The Gramps media object is a collection of data about the media object file: its filename and/or path, its description, its ID, notes, source references, etc. These data do not include the file itself.

The files containing image, sound, video, etc. exist separately on your hard drive. These files are not managed by Gramps and are not included in the Gramps database. The Gramps database only stores the path and file names.

This tool allows you to only modify the records within your Gramps database. If you want to move or rename the files then you need to do it on your own, outside of Gramps. Then you can adjust the paths using this tool so that the media objects store the correct file locations.


From the Introduction page selecting the Next button (or using the keyboard shortcut Alt+N) you will be shown the Selection page window.

Fig. 12.27 Selection - page for "Gramps Media Manager" - Tool wizard - default

From the Selection page window select from one the four options the actions you want to take and then select the Next button:


Replace substrings in the path

Fig. 12.28 Replace substring settings - page for "Gramps Media Manager" - Tool wizard - default

This tool allows replacing specified substring in the path of media objects with another substring. This can be useful when you move your media files from one directory to another.

Selecting this radio button will bring up a Replace substring settings window where you can type in any string in the Replace text field and the With text field. At any time you can click on the Cancel button or the Back button. Clicking the Forward button will bring up the Final confirmation window.


Convert paths from relative to absolute

Fig. 12.29 'Convert paths from relative to absolute':"Final Confirmation" page for "Gramps Media Manager" - Tool wizard - example

This tool allows converting relative media paths to the absolute ones. It does this by prepending the Base path for relative media paths: as given in the Edit > Preferences > General tab, or if that is not set, it prepends the default User's Directory.

Convert paths from absolute to relative

Fig. 12.30 'Convert paths from absolute to relative':"Final Confirmation" page for "Gramps Media Manager" - Tool wizard - example

This tool allows converting absolute media paths to a relative path. The relative path is relative viz-a-viz the base path as given in the Preferences, or if that is not set, user's directory. A relative path allows to tie the file location to a base path that can change to your needs.

Add images not included in database

Fig. 12.31 'Add images not included in database':"Final Confirmation" page for "Gramps Media Manager" - Tool wizard - example

Check directories for images not included in database, this tool adds images in directories that are referenced by existing images in the database. You will have to import one media item from each sub directory manually. Media Manager does not include sub-directories automatically. All the directory paths shown in the tool will be searched through.

Not Related

Fig. 12.32. "Not related to '...'" - dialog - showing results for "Not Related" Tool

This report will find people who are not related to the selected active person.

You can use this tool via menu Tools->Utilities->Not Related....

You will get a Not related to '...' results dialog which shows a list of all the people that are NOT related to the selected person.

This list gives you:

  • Name
  • ID
  • Parents
  • Tags

From the Name column you can use the right arrow button and down arrow buttons to collapse or expand the grouped Name list. Double clicking on a person will bring up the person edit dialog or family edit dialog.

If you select a person you can use the Tag text field(you can fill in whatever custom tag name you want to use) or use the drop down list to choose an existing tag eg TODO, NotRelated. Use the Apply to add the selected tag to the person(s). This tag will then show up in the Tags column.

Relationship Calculator

Fig. 12.33 "Relationship to '...' " - dialog - showing results for "Relationship Calculator" Tool

You can use this tool via menu Tools->Utilities->Relationship Calculator....

Selecting the Relationship Calculator tool will open a list filtered to all people connected, but not necessarily related, to the Active Person. To calculate relationship to different person, close the window, make that person Active and select the tool from the menu again.

Select the individual from the filtered list to report if a relationship exists. The exact relationship will be shown in the lower panel along the the common ancesors of that's reported relationship. Only blood relationships will display (except for husband-wife relationships). Note "in-law" relationships are not displayed.

The filtered list will grouped and alphabetically sorted by surname. (Regardless of whether the View menu setting of the Person category has been set to Grouped.) The list columns cannot be re-sorted.

The degree of separation (generation distance) that will be recognized is controlled by the the Max generations for relationships value in the General tab under the Edit->Preferences... menu. (The default of 15 generations will report a 12th great-grandparent relationship but not their parents. The active person is counted as one of the generations.)

Essentially, any two people are directly related by blood if they have an ancestor in common. One of these individuals may actually be an ancestor of the other - such as a great grandparent. Even in the cases of aunts and uncles, you still can calculate the relationship by searching for the common ancestor. In this case, the father or mother of the aunt or uncle will be a grandparent to the nephew or niece.

The most basic blood relationship through common ancestors is that of siblings (brothers and sisters) who are only one generation down from the common ancestor. Another special relationship is that of one of those siblings to the descendants of the other siblings. If the Active Person is a grandchild of the common ancestor, the sibling would be an aunt or uncle. Beyond that generation of descendants, there are two equivalent ways of describing the relationship. The daughter of great grandparents might be called either a grandaunt or a great aunt. (The Relationship Calculator uses the 'grand' variant.) That person is a great grandaunt to the second great grandchildren, who are four generations distant from the common ancestor. (She may also be called a second great aunt.) The reverse reationship of an aunt or uncle is a nephew or niece.

Cousins (also called "first" cousins) are two generations down from the common ancestor through different siblings. "Second" cousins are thus, three generations down from the common ancestor - and so on.

After that, everyone is considered a "cousin", but to indicate that they are not in the same generation we use the word "removed" to indicate the number of generations different between the two. For example, my father's "first" cousin is also my "first" cousin but "once removed" (one generation difference between us). My fathers "first" cousin is my own child's "first cousin twice removed" - two generations different.

If multiple blood relationships exist due to pedigree Collapse, all will be reported.

A full text list of all blood relations and their spouses can be viewed using a Kinship Report.

See also:

  • The third party Deep Connections gramplet if installed will list the intervening generations to the common ancestor but it does not list the common ancestors. It also lists the indirect relationships.


Verify the Data

Fig. 12.34 "Verify the Data..." - "Data Verify tool" dialog - "General" tab - defaults

This utility allows you to verify the database based on the set of criteria specified by you.

For example, you may want to make sure that nobody in your database had children at the age of 98. Based on common sense, such a record would indicate an error. However, it is not a consistency error in the database. Besides, someone might have a child at the age of 98 (although this rarely happens). The Verify tool will display everything that violates your criteria so that you can check whether the record is erroneous or not. The ultimate decision is yours.

Select this via the menu Tools->Utilities->Verify the Data... you will get a Data Verify Tool window. The window has four tabs; General, Women, Men, Families. Those tabs show a list with criteria and a input field where you can alter the criteria value. In the lists below I show some workable values.

Verify the Data tab pages

Select the criteria you want to run the tool with from the following tabs. If you are OK with the criteria click the Run button (or hit Alt+R and you will be presented with a Data Verification Results window.

Depending on your criteria and your data a list will be shown. Some possibilities of findings are listed below. But there are others.

  • Disconnected individuals (ones with no parent or spouse or child or sibling)
  • old/dead father
  • marriage after death/ before birth
  • large year span for all children
  • early/late marriage
  • young/unborn mother
  • husband and wife with the same surname
  • same sex marriage/ female husband
  • ...
General
  • Maximum age: 90
  • Minimum age to marry: 17
  • Maximum age to marry: 50
  • Maximum number of spouses for a person: 3
  • Maximum number of consecutive years of widowhood before next marriage: 30
  • Maximum age for an unmarried person: 99

The first check box: Estimate missing or inexact dates causes the tool to accept a baptism date if a birth date is not known, and to accept a burial date if a death date is not known. It also causes the tool to accept "inexact" dates (i.e., any "legal" Gramps date which is not a fully-specified one (with an explicit day and month and year)).

The second check box: Identify invalid dates will check if the dates are invalid.

Women
  • Minimum age to bear a child: 17
  • Maximum age to bear a child: 48
  • Maximum number of children: 12
Men
  • Minimum age to father a child: 18
  • Maximum age to father a child: 65
  • Maximum number of children: 15
Families
  • Maximum husband-wife age difference: 30
  • Maximum number of years between children: 8
  • Maximum span of years for all children: 25


Data Verification Results window

Fig. 12.35 Data Verification Results window.

After you run the tool you will be presented with the Data Verification Results window.

On the bottom of the window four buttons are available to make a selection easier. Those are Mark all, Unmark all, Invert marks, and Hide marked.

Double-clicking on a row will give you a possibility to view and or edit the data.

With the Close button (or select the keyboard shortcut Alt+C) you close the Results window.

Examples

Two examples from using real data with this tool:

  • The warning showed 'female husband': checking the data I found a family with father : Anna Roelants. Luckily in the Description I read: The marriage of Adam Roelants and Cornelia Crabbe. It was clearly a typo: Anna i.s.o. Adam. Without this Tool it would be very hard to find.
  • The warning showed 'late marriage': checking the data: male person °1738 female person °1756 : marriage X 1804 [Gregorian Calendar] : Everything seemed to be OK: so they (re)married at the age of 66 and 48 years! The warning showed up because the General criteria was set to 60.

Difference between Verify the Data tool and the Check and Repair Database tool

The Check and Repair Database tool detects inconsistencies in the database structure. The Verify the Data tool, however, is detecting the records that do not satisfy your particular criteria.
