The Power of Ancestry DNA circles

My cousin DM got a new 3rd cousin match, DB, on her Ancestry.com DNA page that was listed in two of her DNA circles even though those ancestors did NOT appear on that match’s tree! Wow, is ancestry really able to make this call just from the DNA? There is no shared ancestor hint with my cousin. (By the way, each member of the couple who provided the DNA gets their own circle; in this case Sigri and Bard Nelson.)

After looking at DB’s tree I see that he has a Selmer Nelson on his tree who is a known descendant of the couple Bard and Sigri Nelson(Nielsson) who make these two circles. So he clearly does belong and his tree just does not go back that far.

Using the shared matches tab on this match’s page, I find that this new match, DB is in common with yet another match in these two DNA circles, BK with whom he is more closely related; they both have Selmer Nelson as a grandfather. BK does not have a green leaf with my cousin JM because he has spelled Bard Nelson and Sigri differently.

However BK is also a shared match with DK who DOES have a green leaf DNA ancestry hint with my cousin. DK shares Selmer’s dad J.B. Nelson with DB and BK. Aha, perhaps that is how this was figured out. Both BK and DK have Bard Nielson in their trees but DK spelled it the way we did. Now perhaps I understand how Ancestry put DB and BK in these circles!

How my Cousin J(M) is related to DK

There are also many more people in this circle some of whom I had already found with those DNA match green leaves. I do love working with my perfect cousin’s DNA. She has no endogamy and such clear cut matches which make great examples. This is my third blog post using her data! Thank you so much JM for testing!

UPDATE: You can have a DNA match in a circle but without a green leaf when they are part of a family group that is in that circle. So my next question was ‘How are family groups determined?’ The answer I got from a friend at Ancestry was: ‘If we find two or more people whose trees and DNA matches suggest they’ve inherited lots of DNA from a recent common ancestor (parent, grandparent, great-grandparent), we create a family group. Within it you’ll see parents and their children, grandparents, aunts and uncles, and first cousins … the ? [in the blue circle at the top] on your DNA Circles opens up 16 help topics. Family groups are explained in topic 7.”

Warning, another user on Facebook pointed out that this may not work so well in endogamous populations and gave an example from her convoluted tree…

  1. I’m BK. Stands for BEAREKEN. Beare is my nickname and KEN are my initials. Keith Eugene Nelson. My dad was Selmer Nelson Jr. His dad was Selmer Sr. And through Jen’s Nelson to Bard/Baard and Sigri.

    • And here I was trying to preserve your privacy! Lovely to meet you Beare. I found this circle with no hint thing fascinating!

  2. Just curious. I have a DNA circle for an Uncle. All the rest are Grandparents. Why would I have one for an Uncle?

    • And most of my circles are based on great-grandparents or great-great grandparents. The idea is that it is a circle of people with whom you share DNA and your uncle would be one of those. Although the circle should be for his parents ….

  3. How can I look for DNA circles I am not related too. Stuck on tracing my surname past one man. If I can start looking at DNA circles for folk beyond tied to the line but at a greater distance in the past…hmmmm I have several circles in other lines to the 4th great but the one I am interested in only goes to the 2nd.

    • Wayne –
      You do not usually get circles for ancestors that are not in your tree. The case in this article was unusual and involved many many people with shared DNA from those common ancestors. You might get some new ancestor discoveries (NADs) for people not in your tree but these are often descendants of your actual ancestor.
      To break through that brick wall of your 2nd great grandad you may need to use the techniques pioneered by adoptees. Go over to DNAadoption and start reading or take a class. You can also try the method used in my GWorks outline here http://blog.kittycooper.com/2017/06/my-adoption-workshop-and-a-success-with-gworks/
