=== Adding the Consanguinity Gramplet ===
The {{man label|Consanguinity Gramplet}} is designed to be added to the sidebar {{icon|rela}}[[Gramps_{{Version manualman version}}_Wiki_Manual_-_Categories#Relationships_Category|Relationships Category]] (''Grouped'' or ''List'') view modes of Gramps. (After [[{{man version}}_Addons#Manually_installed_Addons|manually installing]]<!--[[Third-party_Addons#Installing_Addons_in_Gramps|installation]]-->, this gramplet will be available for addition in all these locations: the [[Gramps_{{man version}}_Wiki_Manual_-_Gramplets#The_split-screen_Sidebar_.26_Bottombar|sidebar/bottombar option]] for the following views: {{icon|peop}}People, {{icon|rela}}Relationships, {{icon|ance}}Charts, and {{icon|geog}}Geography.)
Select the {{man menu|Consanguinity}} menu option from the {{man menu|Add a gramplet}} submenu of the [[Gramps_{{man version}}_Wiki_Manual_-_Main_Window#Gramplet_Bar_Menu|Gramplet selection menus]]. Accessible by pressing the {{man button|&or;}} (''Down Arrowhead'' button) in the view's sidebar or bottombar.
{{man warn|1=Importing can create a mess!|2=Be careful that you do NOT import the [[Example.gramps|example.gramps]] data into your own Family tree. Cleaning out the contamination of records related to thousands of fictitious people would be troublesome. Always double-check which tree is already loaded before importing a file.}}

The example tree included with Gramps includes a few instances of Pedigree Collapse.

=== Explore the common ancestry ===

=== The Relationship diagrams ===
[[File:ConsanguinityDiagramConsanguinityGramplet-51DisplayDescendants-window-example-60.png|thumb|right|450px|Fig. {{#vardefineecho:figure|{{#expr:{{#var:figure}}+1}}}} "Consanguinity Gramplet" - display "Descendants" window - cousins diagram window (click a Relationship hotlink)]]
Clicking the described {{man label|Relationship}} will open a block diagram of that instance of pedigree collapse and how it relates to the Active Person.
In the example ''shown in Figure 12'', Piatt Warner's great grandparents (Edward Warner and Mary Molly Anderson have the {{man label|Relationship:}} '''''second cousins once removed (down)''''' who are descended from the common ancestors, Edward Christiansen and Elizabeth Thomas. Clicking that relationship description opens a basic chart ''(shown in Figure 23)'' of their common ancestors and Piatt's relationship through them.
=== The Pedigree list ===
A text list is more actionable when sharing with family and other genealogists than a diagram. A diagram makes understanding the relationship easier. But a list can be transcribed into a form or another program more easily.
An example of Piatt's pedigree is shown in Figure 34. You will notice that the lines for ancestors 152 and 153 are marked as being the same as ancestors 68 and 69 (Edward Christiansen and Elizabeth Thomas). This is where there is pedigree collapse for Piatt. The rest of the list will crop out the ancestors of 152 and 153 because they too are duplicated.
But which children were the siblings? Just divide the ancestor number by 2 to get the number of their child. Half of 152 is 76 (Nathanial Christiansen) and half of 68 is 34 (off-screen in Figure 3 4 but this is Joseph Christiansen). You can use this method in any Ahnentafel Numbering System. You can also use [https://wikipedia.org/wiki/Ahnentafel#Deductive_reckoning "deductive reckoning"] determine their exact relationship to the #1 person by their number.
