Cite Your Sources (Source Footnotes)

See also United States, How to Find Genealogy Records



Source footnote citations help us document, organize, and analyze the evidence gathered. They are the hallmark of quality family history.

Ideally, every event on a family group record would have one or more source footnotes. The information about the event came from somewhere (even if it was guessed), and that source should be cited properly. When you attach sources to Family Tree on FamilySearch.org, you can print a family group sheet with sources from the individual record of each person. The version printed from FamilySearch.org will vary slightly from family group sheets printed from genealogy software.

Value of Source Citations
The best way to judge the quality of a family group record is by its source footnotes.

Citing your sources makes it easier to correlate and analyze sources against each other. It helps other researchers vet your work. It is a partial acknowledgment of the contributions of the authors you cite. Citing sources is the best way to avoid plagiarism. Also, the source in which an ancestor appears is one of the identifiers of that ancestor (like his name, date, place, and relationship identifiers).

When to add source citations
Add a source citation every time you add an event to a family group record. Add a source citation for every event mentioned on each source. The best time to enter source footnotes is at the same time as you enter the event information. Document AS YOU GO!

Link each source citation to the event(s) it documents. For example, a marriage license may also divulge birth information and should be cited for both the marriage and the birth. Cite the census source for each member of the family listed. (This is easily accomplished by using genealogy software such as RootsMagic. See Creating Custom Reports with RootsMagic on this page. PAF is no longer available.)

What to Cite
In theory a good source citation is simply a matter of including five normal, and two optional elements:


 * Author
 * Title
 * Repository (for publications the place published and publisher; for unpublished material the repository and address)
 * Date
 * Page


 * Optional library or archive call number
 * Brief preliminary evaluation comment about the source (optional, but especially valuable)

In practice the first five elements are sometimes complicated and may be hard-to-find details. For example, who is the author, what is the title, and what is the date of an untitled parish register kept over many years by several ministers?

Most archives and libraries have already used these elements to describe the source in their catalog. So using the repository catalog helps the researcher cite the elements of the footnote in a way that will help other researchers find the same source at the same repository.

On the other hand, as researchers rely more and more on the Internet, new questions arise about how to cite sources from a “repository” that changes so often.

Source Footnote Style Guides
There are several handbooks that can help you improve the style of your source footnotes. They are guides, not commandments from deity. They differ slightly in their suggestions. Please encourage your fellow researchers to cite sources, and avoid being overly fussy about the minutia of their citations. If you see a citation that needs improvement, encourage the author to consider one or more of these guides:

Citation Examples
Here are some idealized example citations as they might appear in the Sources field of a Family Group Record printed using the Personal Ancestral File (PAF) program. These footnotes mostly follow the Chicago Manual of Style. Following the first citation in each category there is a list of the fields used in the PAF Edit Source and Sources—Citation Detail windows to create that source footnote. All footnotes in this list are only models—other researchers may choose different ways to render the same footnote information.
