Two cousins recently chatted after learning that they share DNA. The first asked whether the second is white. “No,” she answered. The response: “Are you sure?”
In our modern society, families are defined in a myriad of different ways. Using DNA for genealogy is certainly contributing to these

changing definitions, as families find themselves genetically linked across social and cultural boundaries to kin they never expected.
Such is the case for a Bartow, Florida resident who submitted a DNA test out of curiosity and found more than she expected. Through a combination of DNA testing and social media, Mary McPherson, who is white, met one of her cousins, Dolores Washington-Fleming, who is black.

According to an article on The Ledger, the two women share a great-great-grandfather, Peter Edward Williams, who was born in South Carolina two centuries ago. Peter was a slaveholder. The 1850 census slave schedule shows that he held a female slave who was a few years younger than she was. Dolores believes that’s her grandmother’s grandmother.
The two finally met this past May for the first time and enjoyed this new definition of family. I think what I like most is what Dolores’ son said about the situation: “My mom and I are fascinated by history, and this is history. We represent what the times were like back then.” It still boggles my mind just a little that we are able to use the DNA of living people today to resurrect the past, and bring depth and meaning to the present, and possibly even prepare us for the future.
I find myself in a similar situation to Dolores and Mary. My mom was adopted, and even though we have had DNA testing completed for several years, we didn’t have any close matches, and honestly, we weren’t looking. Though she did have a passing interest in her health history, my mom did not feel the need to seek out her biological family. But then over the last few months various pieces of her puzzle have started to fall into place. This is much because of a key DNA match that popped up in March.
With that one match and subsequent correspondence, our interest in my mom’s biological family has skyrocketed. Why? I think it is because our DNA match, sisters from Texas, have shown us genuine kindness and interest. They have truly shown us what it means to be family. Even though we are unexpected, even though we aren’t sure yet how exactly we are connected, they have embraced us without reservation without hesitation.
To me, this is what family is. They accept you in whatever condition you come in and do their best to make you feel like you belong. Now, that kind of welcome isn’t felt by everyone who meets their genetic cousins, and people should carefully consider whether they’re ready for unforeseen results or unanticipated reactions from DNA matches before they get started.
But what about you? If you’ve started down the genetics path, how has DNA testing expanded or strengthened your definition of family?

The Family Tree DNA ethnicity report has been updated, and this means more details about ethnic and geographic origins for both autosomal and mtDNA DNA testers.
Family Tree DNA recently announced a round of updates to myOrigins, its mapping tool for ethnic and geographic ancestry. New are more detailed breakdowns of their population clusters and in-depth descriptions of them. (Visit Family Tree DNA’s website here.)
It is so exciting to see new or updated reports from our genetic genealogy testing companies! It is a good reminder of two things: First, that the results we currently have, especially in the arena of our ethnicity results, will continually be improving. Second, that once you test with any company, these improvements are added to your account and your results are updated automatically.
Family Tree DNA is the only company offering a complete look at your mitochondrial DNA (mtDNA), the one that traces your direct maternal line. They recently updated the deep ancestral assignments for these mtDNA tests. The updates were based on scientific advances in the world of mtDNA and can sometimes give you a more specific idea of where your ancestral line came from.
In addition to the mtDNA updates, FTDNA has also updated their MyOrigins results as part of your autosomal DNA test. Previously your MyOrigins results broke up the world into 18 different pieces and you were told your affiliation with each. Now with 6 new populations added, there are a total of 24. The changes include splitting three categories into smaller parts, like they are now reporting Finland separate from Siberia, as well as adding three new categories in South America, West Middle East, and Oceania.
Your MyOrigins results will now also include trace amounts, which are those percentages that are very low and therefore do not carry a high confidence. But many genetic genealogists wanted to see any area that may have been detected, and so FTDNA responded.
How to Review Your Family Tree DNA Ethnicity Report
1. Log in to your Family Tree DNA account. From your dashboard, select myOrigins.
2. On the myOrigins page, click View all to see your full ethnic percentages, as defined by Family Tree DNA. You can also click View myOrigins map to see your results mapped out. (The map looks like the one at the beginning of this post.)
3. When you click to view all your ethnicity results, you’ll see a more detailed breakdown of your population groups. Click View all population descriptions to read more about each one.
The Impact of Updated Family Tree DNA Ethnicity Reports
On the whole, are these updated results going to significantly impact your family history research if you have tested at Family Tree DNA? Likely not. The greater impact is just in the idea that these things can be improved, updated, and changed, which means our experience will continue to improve, and more people are likely to test. More people in the database means more possible cousins. More possible cousins means more genealogy breakthroughs, and a more complete picture of our heritage, and that is what we are really all after.

The Daughters of the American Revolution (DAR) accepts limited DNA evidence to prove descent from a Revolutionary War veteran. In my opinion, the DAR DNA policy is a little too limited. Here’s why–and what you can do.
Membership to the Daughters of the American Revolution (DAR) has been a holy grail for U.S. genealogists for 125 years. With its requirement of proof of a “lineal bloodline descendant from an ancestor who aided in achieving American independence” in three categories: birth, marriage, and death, as well as proof of Revolutionary War Service, membership is exclusive to those with an iron-clad paper trail.
That is, until 2014, when the DAR added DNA evidence to its list of acceptable documents proving a relationship to a Revolutionary War ancestor.
What does the DAR DNA Policy Accept?
The DAR only accepts one of the three forms of DNA testing which is the Y chromosome test, or YDNA. The YDNA traces only a direct paternal line, making it a great choice when trying to link living males with their Revolutionary counterparts. This YDNA is basically passed unchanged from generation to generation, making the modern day holder of the YDNA the proud owner of possibly exactly the same YDNA that fought the Redcoats. That’s pretty cool, don’t you think?
The DAR recently announced that to further help those wanting to use their YDNA as part of their application, they have formed a project at Family Tree DNA, the company that provides the YDNA testing. Projects are absolutely the best way to get the most out of your YDNA testing. There are surname projects, location projects, haplogroup (deep ancestral group) projects, and even special interest group projects, such as this one for the DAR.
While the results of the testing are only available to members of the group, the statistics page gives us an idea of the scope of this project. They currently have 1,242 total members and what looks to be about 430 YDNA tests completed (though it is admittedly difficult to tell based on the chart online.) This means if you think your paternal line may be a candidate for the DAR, you can have a representative of your line tested and compared to the group. If you find a match, you will have relative certainty that you do connect to that Patriot, and can then be more confident in your traditional research in pursuit of the necessary paper connections.
In April the DAR opened up project membership to include mtDNA and autosomal DNA. They will not be using these two kinds of DNA in their applications (yet), but hopefully this project will pave the way for the addition of those tests in the future (though, for several reasons, inclusion of these tests in the application process will be more difficult.)
Though, in all honesty, they have made the YDNA process difficult enough. Let’s say that you are actually able to trace down multiple generations to find a direct male descendant of your Revolutionary guy to be tested, an individual who is, the DAR mandates, “sharing your maiden name or your mother’s maiden name,” and you convince that unassuming relative to give up his saliva, you still are only half way there. The DAR guidelines also state that you have to have a second individual who is “a descendant of the same Revolutionary War ancestor through a different unbroken male lineage that has been previously proven on a DAR application…” (I added the emphasis here.)
A Practical Example of the DAR DNA Policy
OK, so let’s say you are a genealogical whiz and, let’s face it, you were lucky, and you find two such candidates and have them tested.
Well, the DAR tells us that those two men must match EXACTLY on the 37 YDNA markers tested. Now there is no telling when that YDNA might experience a mutation. So to me it seems a little unfair to require perfection. So it is possible, that even after all the work of finding the right guys to be tested, the test itself may work against you, as even one difference is enough to keep this YDNA off of your application, at least for now.
So while I applaud the DAR for using YDNA testing at all, and for spearheading a special interest project at Family Tree DNA, the reality is that the limitations of direct paternal line genealogy and the requirements of testing make it unlikely that very many will be able to take advantage of the YDNA in their DAR applications.
However, there are a few things you can take away from this article now:
- First, collect those DNA samples whenever you can, especially for key relatives, like your paternal line and the oldest living generation (whose DNA is less likely to have experienced any mutation.)
- Second, keep your research paper trail strong. Nothing in the near future of the genetic genealogy industry tells us that distant relative connections (like to your Revolutionary War ancestor) will be provable by DNA alone.
- And third, definitely look at crowd-sourced studies for your particular DNA. Those surname, location, haplogroup, and special interest group projects I mentioned from FTDNA are just some of the ones that might help your research—or that you could use to help someone else’s. I’ve talked about these studies before: click here to read about them.
