It’s working again! At last …
You can upload your DNA test results from Ancestry.com and/or 23andme to Family Tree DNA again! You get a free look and then can pay a mere $19 to get all the tools and information.
Click here for an old blog post of mine for help on getting your DNA data and transferring it. You have to be logged out of any account you have there with family finder results (mtDNA and Y are OK), before you upload. First you sign up for a new username and password (each test result has its own log in). Also be sure to use the zipped download of your data.
I recommend that you download your raw data again to do this. When I rezipped an old ancestry file and tried it, I was told that it was the wrong format but when I downloaded it again, the new version worked just fine.

There is a Valentine’s Day Sale at 23andme.com for American users, $20 off for up to two kits until Feb. 14 which brings down the price for the ancestry only version to $79, more in line with the other companies.
In other news, rumor has it that non-American users will finally be transitioned to the new experience in the next few months. If anyone from 23andme is at Rootstech this week, I will ask for more specifics on that.
Meanwhile there are several new features at 23andme for those of us, Americans, on the new experience:
- The automated triangulation feature now shows all DNA relatives, not just open sharers, and includes anonymous users with a link to request a share.
- Ancestry composition includes a timeline indicator making a guess as to when your ancestor with that ethnicity might have lived.
Click the read more for the details on these. I confess, I am at Rootstech right now, so not there is not much time to write about these in depth, just a few thoughts and images.
Rootstech is almost here and I can’t wait. It is not just the great talks that I love but also all the wonderful displays, shows, and tools in the exhibit hall and, of course, seeing old friends. Naturally I am going in a day early to spend time in that wonderful Family History Library, practically next door to the conference!
My talk is about triangulation, a technique used with DNA test results to prove descent from a common ancestor. I hope to see you there, Thursday at 11:00 in the morning in Ballroom J. As always my slides will be posted at slides.com/kittycooper after the presentation.
Wold line cousins Kitty (me), Ed, Marlys
If you have been to previous versions of this presentation, there will be much that is new this time around. It is amazing how much the DNA technology for triangulation has progressed in just a year. Most American 23andme kits are now on the new experience which includes an automated triangulation feature. Plus GEDmatch has added Triangulation Groups (TGs) to its Tier 1 tools.
Furthermore one of the semi-finalists in the RootsTech 2017 Innovator Showdown is a new Double Match Tool from Louis Kessler that provides triangulation for different ftDNA kits that you have the Chromosome Browser Results (CBR) for. Click here for his blog and description of DMT. Genetic genealogy has come a long way!
There is also news for those of you who remember the story of how I used triangulation to confirm a thin paper trail and prove that Kristine is my Wold side cousin (click here for that blog post and here for the follow up). The DNA test for Marlys, one of Charlie’s 26 grandchildren, came in and provides further proof. Not only that but Marlys had known the story all along about that first child of Charlie’s!
This is the story of how I helped a Jewish adoptee find his birth family using DNA testing.
DNAadoption.com helps adoptees with DNA, including classes
First, here is a simplified explanation of the technique that an adoptee uses to find his birth parents using DNA:
- Do an autosomal test at each of the main companies. Once the results are in …
- Look through the family trees of 2nd, 3rd, and 4th cousin DNA matches for a common ancestral couple or two.
- Build private, unsearchable family trees down from each common couple to find someone in the right place at the right time.
- Get other people on those lines to test when their results will narrow it down some more.
- Males can also do a Y DNA test which might give them a surname if there are any close matches.
Obviously the more you know about the birth parents the easier this is. For more details on this technique see http://dnaadoption.com/index.php?page=methodology-for-autosomal-results or sign up for a class there.
Sadly these DNA search methods do not work well for adoptees from endogamous populations, such as Ashkenazi Jews (AJ) because everyone in that group shares as much DNA with each other as a 4th or 5th cousin. Even worse, most Jewish family trees stop at the grandparents or great grandparents because they do not continue across the ocean. Another problem is that even second cousins can have different Americanizations of their original surnames and let’s not forget that surnames are very recent in this population, about 1815 for most.
That is why there are so very few jewish adoptee successes, so I am celebrating this one with a blog post.
The DNA Search Story
I got an inquiry from, let’s call him Roger Stein, an adoptee curious about his birth parents who matched a cousin of mine at GEDmatch. GEDmatch is a site where you can compare tests done at different companies. His story follows, with all the names changed for privacy. If you do not want the DNA details just skip to the section titled “Contact.”
When you are home and sick in bed what better to do than catch up on reading your favorite DNA blogs? So I decided over today’s bowl of chicken soup to make a page listing the blogs I like to read. It is listed under Resources or click the image on the left.
Also I feel guilty since I am so behind on my own blogging when there is so much news to report. So here are my favorite recent reads to replace my lack of posts:
Legacy Tree Genealogists is releasing their free grandparent/grandchild DNA mapping chartmaker tomorrow, Monday (yes I helped, yes the code is based on my mappers, yes I am an affiliate)
Roberta Estes has a new post on segment size and false matches in her terrific concepts series
She also gives the new 23andme ancestry timeline feature the thumbs down. I do not completely agree with her assessment but as my own post on this is unfinished, perhaps read hers …
Blaine is doing a study that I need to send to all the adoptees I have worked with to fill out
Amy Johnsons Crow’s post on DNA testees and genealogy
Debbie Kennett reports on her Living DNA results
And to tantalize you (I hope), here is a list of my in progress unfinished posts:
- A jewish adoptee finds his birth family in spite of endogamy with DNA and my help!
- New Tier1 features at GEDmatch
- The New Grandparent Mapper released by Legacy Tree Genealogists
- The 23andme new ancestry timeline feature
- Ancestry shared DNA from member profile feature
- DNA.land follow up
- Exploring 23andme transferred results at WeGene.com for an asian adoptee
- My Updated Triangulation talk for Rootstech
Now back to bed with my latest science fiction read …
