DNA2Tree: Build Trees from DNA Matches

Since I do not have an iPad, iPhone or any other Apple device, I could not evaluate this product. It sounds like a real game changer for adoptee searches! Like the DNAgedcom.com client, it finds common ancestors and can make cluster charts. However it goes a step further and shows you the common ancestors for each cluster and can build those ancestor’s trees for you! Here is a guest post from a beta tester. – Kitty

DNA2Tree: New Adoptee Search Software by Jason Schneir

There are approximately 120,000 adoptions each year. When these adoptees become adults a substantial percentage want to find out more about their biological parents. Unfortunately, state privacy laws often stand in the way of identifying and learning about their biological relatives.

DNA testing has proved a boon to adoptees wishing to find their biological family. In the best case an adoptee is tested and the adoptee’s biological family is also tested. For those lucky individuals, finding their biological relative is just a matter of looking at their match list and seeing a close match. No skill is needed.

For the majority of adoptees, close biological family is not DNA tested. Fortunately, there are DNA search techniques that can find biological parents from other tested relatives. Unfortunately, this methodology takes considerable skill and practice. For that reason, many adoptees find a geeky friend, search angel, or paid genetic genealogist to help them.

In December 2018, my wife Beth and I joined SearchAngels.org and watched every video we could find on using DNA search techniques to find an adoptee’s parents. We were excited to have the opportunity to help adoptees, but were very nervous about whether we could be successful. To our great joy, we solved over ten adoptee search angel cases in our first four months. Beth worked with me on most of my cases – especially the successful ones! A key element contributing to our success was a new IOS app, DNA2Tree, which runs on an Apple iPhone.

We chose our first case carefully in the hope it would be easy. There was a first cousin match and the mother was already found – we just needed to find the father. Almost immediately our simple case fell apart and the complexities began to mount.

DNA makes a Merry Christmas

Yesterday was a very very happy day. Thanks to DNA testing, an 82 year old man who thought he had no kids, now has two wonderful adult children plus grandchildren and great-grandchildren. Merry Christmas Billy (my pseudonym for him)! Here is the story.

An accomplished and successful Florida business woman, let’s call her Cheryl, discovered at her father’s funeral that he was not her biological dad. His relatives told her and were not particularly nice about it. Cheryl knew that her dad, let’s call him Larry, had married her mom when she was three months along, but Cheryl had not known that Larry had a paternity test done and knew that she was not his child. He loved her mom very much, so chose to love and cherish Cheryl as his daughter. They were always quite close.

Her mother was long gone and could not be asked. In disbelief, Cheryl took the Ancestry DNA test to confirm or deny this tale. She also got her half brother, her mother’s son from an earlier marriage, to test. That way she could separate out the matches on her mother’s side from those from her Dad’s line.

Her DNA results had no matches to anyone in Larry’s family, which disappointed her, even though it was not a surprise now. However she found what looked to be a half brother, let’s call him Joe, an adoptee born and raised in Australia. Her other paternal side matches, two second cousins, and several third cousins, all had roots in a small town along the Mississippi River. Surprisingly. the second cousins had no ancestors in common with any of the others. So Cheryl contacted me for help back in early October.

My Adoption workshop and a success with GWorks

Next Friday I am doing a workshop at the SCGS Jamboree in Burbank on using the tools at DNAGedcom and GEDmatch to solve unknown parentage cases. Since I like to have slides that are screenshots for my attendees, I decided to grab a few images using the latest and greatest GWorks on a missing father search case whose maternal half brother’s results were just in.

The basic technique for finding an unknown parent is to search the trees of close DNA matches looking for an ancestral couple shared among many of them. Build the tree down from that couple until someone is in the right place at the right time. The more you know about the unknown person(s) the easier this is. See the top of this post of mine for a summary – http://blog.kittycooper.com/2017/01/a-jewish-adoptee-finds-his-birth-family/

It has been a while since I used DNAGedcom. Why? Because now that Ancestry.com DNA has over 4 million testers, many adoptees get lucky and as soon as their DNA results are posted, they have enough good matches to figure out who at least one birth parent is. Also the use of a mirror tree with a second cousin’s information can often identify the family branch they are looking for (see http://www.borninneworleans.com/how-to/what-is-a-mirror-tree/ for that technique).

However when there are only third and fourth cousin matches, the remarkable tools at DNAGedcom.com can help you solve your mystery, but it is not intuitive or easy. It works best for folk with deep American roots, since that is the most tested population at Ancestry.com.

GWorks is a tool at DNAGedcom designed to automate comparing the people in all the different trees of your DNA matches. With an inexpensive subscription, you can use their “client” to aggregate the results from each different testing site and the people in the trees at ancestry. You can also manually upload Gedcoms which are easy to generate from ahnentafel lists (for that technique see http://blog.kittycooper.com/2016/10/text-to-Gedcom-using-ahnen2ged/ ). Then you get GWorks to compare all those trees looking for common people.

Much to my amazement, as I took screenshots of the GWorks process using my case, I was suddenly able to solve it! And he had NO good paternal side matches! It was all from the trees of fourth cousins. And done in two days using GWorks. (OK, once I saw that I had it, I stayed up until 2:00 am building the tree, I admit it, still…)

So how did I do this?
