DNA Ethnicity Results: Exciting or Exasperating?
Are your DNA ethnicity results exciting, confusing, inconsistent, exasperating…or all of the above?
Recently Kate expressed on the Genealogy Gems Facebook page her frustration with her ethnicity results provided by AncestryDNA. She gets right to the point when she writes, “the way they refer to the results is confusing.”
Kate, you are not alone. Many genealogists have been lured into taking the autosomal DNA test at one of the three major DNA testing companies just to get this glimpse into their past. Remember that the autosomal DNA test can reveal information about both your mother’s side and your father’s side of your family tree. Many take the test hoping for confirmation of a particular ancestral heritage, others are just curious to see what the results will show. Though their purposes in initiating the testing may vary, the feeling of bewilderment and befuddlement upon receiving the results is fairly universal.
Kate has some specific questions about her results that I think most will share. Let’s take a look at a couple of them. First up, Kate wants to know if our family tree data in any way influences the ethnicity results provided. The answer is an unequivocal “no.” None of the testing companies look at your family tree in any way when determining your ethnicity results. However, the results are dependent on the family trees of the reference population. The reference populations are large numbers of people whose DNA has been tested and THEIR family history has been documented for many generations in that region. The testing companies compare your DNA to theirs and that’s how they assign you to an ethnicity (and place of ancestral origin?).
Next Kate asks, “Do they mean England when they report Great Britain?” Or to put it more broadly, how do these testing companies decide to divide up the world? All of the companies handle this a little bit differently. Let’s look at Ancestry as an example. When you login to view your ethnicity results, you can click on the “show all regions” box below your results to get a list of all of the possible categories that your DNA could be placed in. These 26 categories include nine African regions, Native American, three Asian regions, eight European regions, two Pacific Island regions, two West Asian regions, and then Jewish, which is not a region, per se, but a genetically distinct group.
Clicking on each individual location in the left sidebar will bring up more information on the right about that region. For example, clicking on Great Britain tells us that DNA associated with this region is primarily found in England, Scotland, and Wales, but is also found in Ireland, France, Germany, Denmark, Belgium, Netherlands, Switzerland, Austria, and Italy. Basically, this is telling us that people with generations of ancestry in Great Britain are quite a genetic mix from many areas.
The first chart here shows that if we are to test the DNA of 100 natives of one of these primary regions (England, Scotland or Wales) then 50 of them willhave the great Britain “pattern” of DNA covering 60% or more of their entire genome, and 50 of them will have that pattern in less than 60% of their DNA. The fact that this half-way number is so low, only 60%, tells us that there is a lot of uncertainty in this ethnicity estimate because there is so much mixture in this region. Kate, for you that means that when you see Great Britain in your ethnicity estimate, it could mean England, or maybe it means Italy- Ancestry can’t be certain.
But that uncertainty isn’t the same for every region. Pictured here is also the ethnicity chart for Ireland. You can see that half the people who are native to Ireland will have 95% or more Irish DNA. Kate, for us this means that if you have Irish DNA in your results, you can be pretty certain it came from Ireland. From these tables you can see your membership in some regions is more robust than others, and Ancestry is using these tables to try to help us tell the difference.
In the end, the ethnicity results reported by each DNA testing company are highly dependent on two factors: the reference populations they use to compare your DNA against, and the statistical algorithms they use to compute your similarities to these populations. Every company is doing both of these things just a little bit differently.
Kate, if you want to get another take on your ethnicity results, you can take your data over to Family Tree DNA, or you can be tested at 23andMe. A free option is to head over to Gedmatch and try out their various ethnicity tools. If you need help downloading and transferring, you can head over to my website: http://www.yourdnaguide.com/transferring. Most people have found after searching in multiple places that their “true” results are probably somewhere in the middle.
While these ethnicity results can be interesting and useful, for most they will just be a novelty; something interesting and exciting. I have found that their most useful application is acting like a fly on a fishing line. They attract our family members into DNA testing where we can then set the hook on the real goal: family history.
If you’re ready to bait your own hook, I recommend you check out my series of DNA quick guides. These guides will help you choose the right DNA tests for your genetic genealogy questions. You’ll become a smart shopper, more prepared to choose the testing company that’s right for you. And you’ll be prepared to maximize your results from each company, rather than look at them blankly and wondered what the heck you just spent that money on.

The Genealogy Gems Podcast Episode 215
with Lisa Louise Cooke
In this “Blast from the Past” episode, Lisa gives voice to the era of silent films, in a unique approach to understanding her great-grandmother’s life. Her passion for this mostly-forgotten film genre comes through in her conversation with film archivist Sam Gill of the Niles Essanay Silent Film Museum in Fremont, California.

Just after RootsTech 2018, Your DNA Guide Diahan Southard reports on the latest DNA news you’ll want to know.
NEWS: DNA NEWS ROUNDUP
First up was MyHeritage, showing their support for the 7 million adopted individuals in the United States with their new DNA Quest campaign. MyHeritage will provide 15,000 DNA test kits to eligible participants free of charge, in order to help these adoptees use DNA to reunite them with their biological families. With this initiative they “hope to make this project a shining light for corporate philanthropy and an example to be followed by other commercial companies in their own lines of expertise to make the world a better place.” MyHeritage has assembled an advisory board of genetic genealogists and genetic counselors to help drive this project and ensure it meets the needs of the community. If you or someone you know is interested in participating, you can head on over to the DNA Quest website (www.dnaquest.com) to fill out an application. But you better hurry, the application deadline is April 30, 2018.
Next, addressing the biggest problem in genetic genealogy, namely the looming What Next? question facing millions of newly swabbed participants, MyHeritage announced the Big Tree ? a giant network of genetic and genealogy results that will automate much of the match comparison and tree searching to replace your head-scratching with light-bulb moments. They have already made significant headway on this project, as reported in the journal Science, which MyHeritage’s own chief scientific officer Yaniv Erlich collaborated on. The journal reports that the team of scientists successfully extracted public family trees from Geni.com (a MyHeritage daughter company), and then used a computer program to clean up and link the trees together. It sounds like MyHeritage will be adding genetic data to this kind of tree data in their Big Tree project.
MyHeritage isn’t the only company out to improve the DNA matching experience. UK based LivingDNA announced that they plan to add DNA matching to their popular origins test by third quarter 2018. When they launched in October of 2016, LivingDNA was not offering cousin matching, but opted instead to focus all of their resources on providing very detailed origins reports, including breaking down the UK in to 46 categories. In the months since their launch, they have been working on a genetic matching system, called Family Networks, that will appeal to a wide range of users and will “reduce the risk of human error and take away the tedious task of figuring out how each person on a user’s list are related to one another.” They are promising an experience that provides “a level of relationship prediction and specificity beyond anything currently on the market.”
So it sounds like if you are currently struggling with turning your DNA matches into genealogical discoveries, our testing companies want you to know you are not alone, and they are working hard to provide solutions to these problems. Time will only tell if they can succeed.
Diahan also provides answers to questions asked about this blog post announcing updates to MyHeritage DNA matching technology and its new chromosome browser.

INTERVIEW: SAM GILL, FILM HISTORIAN AND ARCHIVIST
Shown here: Sam Gill and Lisa Cooke at the Niles Essanay Silent Film Museum on the day of this interview. Throughout their conversation, you hear the sounds of excited theater patrons filling the auditorium before a screening.
Sam Gill’s interest in silent film dates to 1966, when as a college student he traveled to Hollywood to interview his aging heroes from the silent screen comedy era. For more than 20 years, he was Archivist of the Academy of Motion Picture Arts and Science’s Margaret Herrick Library, where he established the Academy’s Special Collections and helped it grow to its current status as the preeminent repository for the study of American cinema. He is currently a Board Member of the Niles Essanay Silent Film Museum. Over the years, he has consulted on or otherwise contributed his expertise to numerous film festivals, museum film programs and film history books.
Sam recently sent us these delightful photos (below) of himself over the years:
