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.

Preserving your Family History on a World Tree

A heartbreaking moment for any family historian is when you discover that your late genealogist cousin’s wife has shredded all his papers. This actually happened in my family. I can only hope that all the genealogical information was passed on to his children first. I think he had long since given me copies of most of it.

Please don’t let this happen to your work. A good preservation solution is to contribute your research to at least one of the online collaborative world trees.

Several years ago I did a blog post on the advantages of using these world trees (click here) and created a comparison sheet of the big three world trees (updated version at the end of this article): FamilySearch.org, GENI.com and WIKItree.com

I also did a Rootstech talk on this topic (click here for those slides). There have been a few changes since then, mainly around DNA and whether or not you can upload a GEDcom.

DNA connections

DNA features abound at WIKItree.com – you can connect your WIKItree profiles to GEDmatch by putting their kit numbers in. This causes the GEDmatch one-to-many tool to display the blue word Wiki which links to your compact tree. So even though it is the smallest of the three world trees, it may be best for genetic genealogists. Another WIKItree feature is that you do not need to login to see trees and profiles so it is great for sending tree links to new cousins. Plus it shows X and Y descendancy pathways.

GENI can link to DNA profiles at family tree DNA and will even display haplogroups on the person’s page. When you and your DNA matches have your family trees on GENI, you can quickly see how you are related. Click here for the blog post I did on how to link your ftDNA reults to GENI.

FamilySearch does not have any DNA features yet but surely they will eventually incorporate something.

Adding GEDCOMs

The big news is that GENI now has a GEDcom uploading capability again. Whereas WIKItree has dialed back on the GEDcom uploads but still has good functionality.

Make a combined DNA kit for yourself

Have you ever wanted to make a kit combining all your DNA tests at the different companies so as to get the most SNPs for comparisons? Well GEDmatch GENESIS is now providing that for paid members. So of course I made one of these superkits for myself! I combined my LivingDNA with my V3 23andme and my current Ancestry kit. Now to investigate what I have gained from this.

The first thing I did was compare this new kit to my recent Ancestry kit. All looked fine. It has the expected small differences, many of which disappeared (including the black lines) when I checked the prevent hard breaks box on the form. The older 23andme kit comparison had more black spots and mismatches.

My next thought about my new superkit was that I might get a better comparison to cousins who tested more recently at 23andme but none of them have uploaded to GENESIS yet. So I checked how my comparison to an Ancestry tester, my second cousin once removed Jeanie, looked. The superkit gets the same result as my recent Ancestry kit. When I compared her to my 23andme kit and my Living DNA kit however, there were small differences.
