The first rule of genealogy is to Get the source. Often you may have entered information into Gramps without checking or adding the Source for it. This is one way to find those pieces.

How to find all events without a source attachment
There are several levels of source requirements that genealogists.
- Require a source for each Event
- Require multiple source citations for Events
- Require quality sources for citations
Find Unsourced Events
- Go to the Events View
- Create a custom filter
- Select the Filter gramplet in the Events view's sidebar

- Add a new custom filter
- Select "None" from the "custom filter" drop-down list
- click the
edit icon to the right of the "custom filter" drop-down list
- Add a Name to the filter (e.g., "Unsourced Events")
- Add a Comment to the filter
- e.g., you could paste in the URL for this article:
https://www.gramps-project.org/wiki/index.php/How_do_I_find_the_information_that_are_missing_a_'source'_attachment
- Define the filtering "Rule list"
- Click + to add a rule
- Expand the "Citations/Source filters" list. (Older versions of Gramps may have used the "General Filters" list)
- Select the "Events with <count> sources" rule
- Set "Number of instances:" to 1
- select "Number must be:" to "less than"
- Click OK to commit the rule to the rule list
- Click OK to commit the custom filter definition
- Apply the new custom filter
- select your new filter from the "custom filter" drop-down list
- click Find to verify that it works.
Find Events with too few citations
The "proof level" refers to the standard used to establish the credibility of a genealogical conclusion. primarily based on the "Genealogical Proof Standard" (GPS).
According to the Genealogical Proof Standard, relying on one single source is not enough to establish a genealogical fact; you should ideally use multiple sources of different types to corroborate information and reach a solid conclusion, meaning you should consult several sources to achieve "proof" in genealogy.
The reason we used the "Less than" for the "Number must be:" instead of the "equal to" option is so that you could could easily choose a different level with a single edit. So, if your standard is a minimum of 3 citations, merely change the "1" in the "Number of instances:" to 3.
Then click the Find button again with the adapted custom filter.
Find Low Quality Sources
You could add a rule to test for quality (higher confidence) sources in addition to quantity of citations.
Add the rule "Events with at least one direct source >= <confidence level>" to the rule list.
The default confidence level when adding Sources is "Normal". So if the filter rule confidence level is set to "High" or "Very High", then you can manage your source quality objectives.
If you have not yet started managing your source quality, now might be the time to adjust all your "Normal" confidence sources down to "Low" confidence. Then, when you have a chance evaluate the quality, there is room to have a neutral confidence plus 2 additional levels higher confidence. Only 1 level of negative ("Very Low") confidence should be needed. (You can use a Role of "Disproven" for Events known to be incorrect.)
