Have you ever looked at your family tree and thought, โWhere did that information come from?โ
Or looked at a name, date or place in your family tree and wondered whether the information is correct?
Family history source citations are crucial in developing an accurate family history. And yet, missing or incomplete family history source citations are one of the most common problems we all face.
Those missing or incomplete source citations matter. Hereโs whyโand how you can start fixing them.
Why genealogy source citations matter
The main danger of failing to cite your sources is that you won’t be able to verify the accuracy of the data you entered. It may be supported by credible evidence, or it may have been a guess, an assumption, or a copy from an uncited tree.
Without good source citations:
- You canโt tell how reliable the information is
- You wonโt know how to find the sources again
- You wonโt know how accurate your family history is.
Fixing missing citations isnโt just about good habitsโitโs about improving the quality of your family history.
How to fix missing family history source citations
You donโt need to fix everything at once. Start with a manageable plan and a systematic approach. Hereโs one way to approach it:
1. Choose your focus
Itโs a good idea to improve source citations as you work, but you should also implement a systematic review. I suggest working along one grandparent line at a time. That makes it easier to keep track of where you are up to.
2. Review what youโve got
Look at the information listed for each person and check:
Which information has:
- no sources cited, or
- just one source citation.
For information that does have citations:
- Do they contain all the necessary information to help you find the source again? For example, a citation like โbirth certificateโ or โancestry.comโ does not contain all the necessary elements โ see my Six Question Model, below.
- Are they in the correct format?
- Does the source actually contain the information that the citation is attached to?
If the answer is no, mark it for action. Make use of the tagging functions in your family tree software or online tree programs.
If you’re using Legacy Family Tree software, the program makes it easy to find people who are missing source citations.
- Open the Search tab.
- Click on the Missing Sources tab.
- Use the checkboxes to define your search โ for example, you can search for individuals who have no sources at all, or you can search for those who are missing sources for their birth, death and marriage information.
- Click on the Create List button.
- You can save a copy of your search list by clicking on the Options button, then Print, and save as CSV file or a PDF file. I prefer the CSV format because you can open it in Excel and mark off the individuals as you fix the citations.
From here, you can begin reviewing these individuals and fixing the source citations.
3. Add or revise your source citations
If you have a copy of the source:
- examine the source
- generate a source citation and
- attach it to the information.
If you do not have a copy, you will need to research the information again.
Donโt forget to update your tags, so that you know the problem has been fixed.
Once you’ve reviewed and begun correcting your citations, a few tools and strategies can make the process smoother and more sustainable over time.
Tips to make fixing genealogy citations easier
Use examples: Create a sample set of citations for sources that you use frequently, or keep a citation guide handy, such as Noeline Kyleโs book, Citing Historical Sources [1]. You can also use a citation generator, such as Cite-Builder.
Use software tools: Family tree programs let you search for people who are missing source citations. Use these tools to create a list or checklist. Ancestry Pro Tools, for example, has the Tree Checker.
Break it into manageable chunks: You might aim to review one ancestor per week or fix citations for a single surname line over a month.
Measure and celebrate your progress: Watching that long list getting shorter and shorter is a great motivator. Every citation you fix improves the quality of your family history.
Use the Six Question Model: To create a clear, useful source citation, use the Six Question Model from my book, The Good Genealogist.

Improve the quality of your family history with better source citations
It may seem overwhelming โ fixing all those missing or incomplete family history source citations. But every time you fix one you improve the quality of your family history.
Taking time to fix source citations is a chance to correct errors, strengthen your evidence, and feel more confident about the accuracy of your family tree.
It also helps other researchers and family members, by sharing reliable and useful information.
