DNA Evidence to Connect to Your Veteran Ancestors

Memorial Day is upon us. It’s a day to honor those who served in the military.  Maybe you’re a member of the Daughters of the American Revolution (DAR), Sons of the American Revolution (SAR), or another lineage society. Or maybe you would like to join one of these organizations.

As genealogists, you might have papers, photographs, and military records to document your ancestors’ military service.   And you might have records, such as birth certificates, marriage licenses, and the like, to establish your connection to your veteran ancestor.

Have you ever wondered whether DNA evidence can be used to show your connection to your veteran ancestors? This article provides answers to that question, using the DAR and SAR as examples.

DNA and Daughters of the American Revolution

On January 2, 2014, the Daughters of the American Revolution (DAR) announced it would begin accepting Y-DNA as evidence of lineage submitted with DAR membership applications. Now the DAR allows DNA evidence in support of both new membership applications and supplemental applications for the DAR. DNA evidence can be used in combination with other types of evidence, but not alone.

Y-DNA as Evidence

What Y-DNA evidence can be used? DAR staff genealogists will only consider Y-DNA 37 marker test results. (DAR Citation)   Companies like FamilyTreeDNA.com (FTDNA) offer a Y-DNA 37 marker tests. The number 37 refers to how many markers are tested. This is the lowest number that FTDNA tests.

Initially, this acceptance of Y-DNA might seem counterintuitive: on the one hand, the DAR is a women-only lineage society; on the other hand, Y-DNA is DNA passed exclusively from men to their sons. Thus, a Y-DNA test is used to study a man’s patrilineal line (that is, the direct father’s line).

So why use Y-DNA? The DAR’s reasoning on this is provided in its Policy Statement and Background: Using DNA Evidence for DAR Applications. Here it is.

The current accuracy of the 37 marker Y-DNA test does not allow for positively identifying descent from a specific ancestor, but does provide a high degree of certainty (95%) that two living men share a common ancestor at more than 150 years but less than 200 years, if they match at all 37 marker locations.

The DAR provides DNA Test Requirements.  These requirements include the following: submission of Y-DNA test results and other specified information from at least two individuals.

  • The first person is a male relative of the applicant who shares with the applicant (or the applicant’s mother) an unbroken paternal line to the Revolutionary War ancestor. Page 1 of the Requirements has a diagram showing possible male relatives that can be used.
  • The second person must be a close male relative of a member who has a previously verified new or supplemental application through an unbroken male line to a different son of the same patriot. ( at p. 2) Page 2 of the Requirements has a diagram showing possible male relatives that can be used for the second person.

There must be a 37 of 37 marker match between the first and second persons. The DAR states that this DNA matching is evidence that the applicant and the person with the previously verified application both descend from the same patriot. Further details of the requirements are available on page 3 of the Requirements.

Keep in mind that the DAR accepts this DNA evidence in conjunction with paper evidence.

DNA and Sons of the American Revolution

Like the DAR, the Sons of the American Revolution (SAR) allows DNA evidence in support of an application. The SAR’s Application Preparation Manual states that “DNA evidence can only be used as part of a proof argument that includes additional conventional proof of the lineage.”

Unlike the DAR, the SAR allows for more types of DNA to be used, including autosomal DNA. All people regardless of gender have autosomal DNA. This type of DNA is inherited from both parents.

Conclusion on Using DNA Evidence to Support Applications

Way back in 2013, when the Daughters of the American Revolution (DAR) was about to announce its acceptance of DNA evidence, Legal Genealogist, Judy Russell said it was a good start. However, it was very limited and should be expanded.  Agreed! Allowing DNA evidence to prove lineage should be expanded.

Why is DNA evidence less acceptable than paper evidence? We’ve all seen paper records that are incorrect, inconsistent, and incomplete. For example, there are many examples of “misattributed parentage events,” which is sometimes called “non-paternity events.” DNA evidence can be used in these situations.

DNA evidence is used to find birth families of adoptees and others with unknown parents.   When a birth family is discovered that includes veteran ancestors, that person should be allowed to use DNA evidence as part of their lineage proof.

Genealogy leaders are embracing DNA evidence to answer genealogical questions. It’s particularly useful when other proof has been destroyed, such as in courthouse fires, or it is lacking.  For example, Thomas W. Jones, PhD, wrote about using DNA evidence to solve a mystery in his family. (Thomas W. Jones, “Too Few Sources to Solve a Family Mystery? Some Greenfields in Central and Western New York.” National Genealogical Society Quarterly 103 (June 2015): 85-103).

DNA evidence is also useful when other proof is absent, such as during slavery.  Morna Lahnice Hollister described how Y-DNA provided evidence on an emancipated family’s surname.  “Morna Lahnice Hollister, Goggins and Goggans of South Carolina: DNA Helps Document the Basis of an Emancipated Family’s Surname,” National Genealogical Society Quarterly 102 (September 2014): 165-76).

These examples show that DNA evidence is an accepted and proven tool that should be embraced and expanded.
