Ancestry DNA updates its ethnicity estimates

By 1 Comment

On September 12, Ancestry DNA debuted its “enhanced” ethnicity estimates based on a much larger reference sample (16,000 versus 3,000 reference samples) and improved algorithms. Blaine Bettinger, The Genetic Genealogist, has a great blog post explaining it.

Comparing my own older and newer ethnicity estimates, fewer ethnicities are represented. My percentage Irish/Scottish has gone up and my percentage Scandinavian has gone down (and the Scandinavian countries are now mentioned specifically). If I’m reading it correctly, ethnicities that represented 20% of the estimate are now gone. Interestingly enough, the new estimate much more closely resembles the MyHeritage estimate I received when I transferred my DNA data there recently (free of charge).

Here is a summary of my old estimate, taken from Ancestry’s site today:

And here’s the new estimate:

And, just for kicks, here’s my MyHeritage ethnicity estimate:

If you’ve tested your DNA through Ancestry and haven’t checked your ethnicity estimate in the last week, I encourage you to hop over there and check it out! (And, if you haven’t already, you can transfer your raw DNA to MyHeritage here.)

By the way, I found this support page on Ancestry that explains how to make the most of your ethnicity estimate. It was news to me, so I thought I’d share.

Understanding genetic genealogy (finally!)

By 8 Comments

Understanding genetic genealogy (finally)I attended Diahan Southard’s series of DNA lectures on July 28 as part of the St. Louis Genealogical Society’s Summer Speaker Series. As I mentioned in a blog post last month, I’ve had a hard time using DNA in my genealogical research, mostly because I have a difficult time understanding and retaining what I try to learn about DNA.

Diahan is an expert on making this information understandable to non-scientists like me. I’ve heard her speak before but this time, a door in my brain cracked open. It may have been because at the seminar we had the privilege of listening to Diahan for four straight lectures, each of which built on the prior one. It was really a brilliant program and Diahan is an excellent speaker.

So I came home and started applying what I’ve learned and I now feel that genetic genealogy is part of my tool box. Hooray!!

Here are some of the revelations from her talks that really helped me:

  • A DNA match with a person whose tree has no familiar surnames is cause for celebration, not frustration. The DNA shows you’re related. When you figure out how you’re related, you’ll add names to your tree.
  • The Shared Centimorgan (cM) Project can help you understand how you might be related to someone, based on how much DNA you share. Here’s Diahan’s explanation of centimorgans and the Shared cM Project. It’s a great resource.
  • The solution to most DNA is quandaries is (drum roll): Do genealogy! DNA evidence can bridge gaps or open holes in brick walls. But traditional genealogy is how you build your family tree.
  • Create a list of your 32 great great great grandparents’ surnames to help you find commonalities with DNA matches. I had not compiled a list like that before and I see how it will help recognize how I might be related to those DNA matches that are fourth cousins or closer.
  • On Ancestry, even if a DNA match has not linked a tree to his/her DNA results (so you see “no family tree”), click on the “View Match” button and see if there’s a drop-down list of trees you might look at under the Pedigrees and Surnames tab. There may be a tree (or a few trees) for you to look at.

One thing I noticed when I took a look my Ancestry DNA results the day after the Diahan’s seminar is that the shared centimorgans don’t necessarily accurately reflect the relationship. For example, my mother’s first cousin, whom I know personally, shares only 183 cM with me, rather than the 439 that first cousins once removed usually share, according to the Shared cM Project. So Ancestry guessed that she was my third or fourth cousin. The Shared cM Project is a great tool, but obviously just a guideline.

Today in my research session, I explored the public tree linked to someone with whom I share 158 cM. This is a huge tree but I was able to easily focus in on a shared surname. The tree is beautifully sourced, so even though I had only a few minutes left of my 30-minute research session this morning, I was able to add a fact and supporting document to my great great grandfather’s record in my family tree software. Tomorrow I’ll go back and explore that tree more.

I finally understand how DNA can help me in my genealogy research. Better yet, I understand how to use it. This is such a revelation.

If using genetic genealogy eludes you as it did me, I heartily encourage you to check out Diahan’s website, Your DNA Guide, and to listen to Diahan speak when you have the chance. She’s speaking at the Federation of Genealogical Societies conference later this month and I know she’ll be speaking at the 2019 NGS conference in St. Charles, Missouri, next May. (I’ll plan to be in the front row!) You can also do a consultation with her where she explains your DNA results to you. She’s a terrific resource.

Giving DNA another chance

By 6 Comments

Confession time: I have the hardest time understanding genetic genealogy. I have spent hours in seminars at various conferences. I even had a one-on-one consultation about my DNA results with genetic genealogist and consultant Diahan Southard, Your DNA Guide.

For some reason, these concepts are hard for me to grasp and retain. As a result, I do very little with my DNA results. I occasionally check matches to my autosomal test (which I did through Ancestry DNA and transferred the results to Family Tree DNA) but that’s pretty much it. Every year I hope (but don’t plan) that this is going to be the year that I harvest the power of DNA in my genealogy research.

An opportunity to learn more was just handed to me on a silver platter. Diahan Southard is coming to St. Louis for a Summer Speaker Series event put on by the St. Louis Genealogical Society on July 28. I just registered. (If you’re in St. Louis and interested in going, today July 10, is the early-bird deadline. Tomorrow the price goes up by $10.)

I know what a great speaker Diahan is and it couldn’t be more convenient for me to go. So I couldn’t turn down the opportunity to hear her speak. (Plus Diahan holds a special place in my heart because she was one of the first people to consent to being interviewed for my How They Do It series.) I’ll be attending her talks on July 28 with an open and curious mind and I’m hoping that they will help me incorporate more genetic genealogy into my research.

If you’re in St. Louis and going, please let me know so we can meet!

Kiss me, I’m Irish!

DNA test. Now what?Last year on St. Patrick’s Day, I wrote a post about my DNA ethnicity results. It seems appropriate to run it again today. Happy St. Patrick’s Day!

I never felt much of a connection to March 17 until I had my DNA tested through Ancestry DNA. Then I discovered in that test that I’m 38% Irish. (That’s my pie chart in the picture.) I knew that Ireland was in my family tree, but I haven’t researched much that far back to realize that it was an important part of my heritage.

Growing up, Irish roots were never mentioned. All that came up was vague mention of England, though in reality our heritage wasn’t much discussed. That’s probably because there were  no immigrants recent enough for my parents or grandparents’ to have known them. We always just felt American.

When I had my DNA tested, it was in an effort to meet cousins and further my genealogical research. (Understanding those results is an ongoing project.) The ethnicity component of didn’t even enter my mind. But today, St. Patrick’s Day, it feels nice to have a kinship with my Irish forebears, though I’m still learning about who they were.

If you’re curious about your own DNA, Ancestry DNA is having a sale–10% off kits through March 19, 2017.

If you’ve had your DNA tested were you surprised by the ethnicity results?
