DNA Triangulation 2017 – My Rootstech Talk

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!

DNA lecture videos are now available from i4GG

Cece Moore organized a conference just for genetic genealogy this past October in San Diego. It was terrific, the only problem was that I could not go to every lecture! Now that the videos are out, I can watch the ones I missed, including my own talk on GEDMatch.

For those of you who did not attend the conference, you can purchase all 19 videos for the amazingly good price of $99 or individual ones for $10 each. Click on the image below to order them. The quality is excellent.

Those of you who were at the conference get them as part of the package so check your email inbox for the link and password.

Back to Basics, My DNA talk this weekend

The Genealogy Society of San Diego is having me give two talks this coming Saturday, one about DNA basics for genealogists and the other about how I broke some brick walls with DNA testing in my own family.

Talking about using DNA for genealogy is something I love to do. While I have lots of posts and pages here, there is nothing like being able to discuss it in person. The questions I get teach me what is difficult to grasp about this shiny new tool in our genealogy kit so that I can better help others.

After the talk, I will put the links to my slides at the end of this article, but they have very few words so they are less useful if you were not there. All my presentation slides are at slides.com/kittycooper and the handouts that go with them are in my downloads area here.

If you cannot make it Saturday, here are a few of my articles on DNA basics, all of which are listed under the DNA testing tab in the top menu above:

A DNA conference and a Methodology for Adoptees

The i4GG genetic genealogy conference is coming to San Diego next weekend and it features a track for adoptees as well as one for genealogists. For those of you who want to hear me speak, I will be doing a talk about the tools at GEDmatch on Saturday morning.

DNA testing has broken many brick walls for family historians and has been a miracle for the adopted, helping them find their biological families where traditional methods have failed.

drozcece3Cece Moore, the i4gg conference organizer, has pioneered this field and has developed a methodology that succeeds over and over again. She described this in her cameo appearance on a recent Dr. Oz episode that featured an adoptee who found her birth family with Cece’s help. Click the image to the left to go to the online clip of the episode.

A simple explanation of the methodology is as follows. An adoptee tests their autosomal DNA at all three major companies (see my DNA testing page) and then uploads those results to all the free third party sites as well. Sometimes they get lucky and find a close family member who has tested and who is willing to help. More often they must look at the family trees of their 2nd and 3rd cousin matches to see what ancestors are in common. Once a shared ancestral couple is found, they build a family tree forward in time, looking to see if one of the couple’s descendants was in the right place at the right time to be the adoptee’s parent.

To learn more about this methodology come to the conference, or buy the videos of it, or go to DNAadoption.com or join DNA detectives at Facebook and read through the files there. Or do all of those things.

Snippets from the SCGS Jamboree

Going to a conference about your passion can be a really fun experience. It is wonderful to finally meet people who you have been emailing with and discussing important issues with online. Another favorite for me is the exhibit hall with vendors showing off their new and old stuff.

I had a great time at the SCGS Jamboree this year. Since I came home early, I am watching a talk streamed live about organizing my work space as I write this! The live stream is really well done. A small live image of the person is on the left and their slide is shown, much larger, on the right. Plus you can chat with the other folk watching. The live stream is available free, thanks to Ancestry.com, until July 5 see http://genealogyjamboree.blogspot.com/2016/05/jamboree-2016-registration-now-open-for.html

Richard and Kalani at the ISOGG booth

In order to pace myself at a conference, I try to limit myself to attending two presentations a day and spend the rest of the time schmoozing in the exhibit hall.

Two people who I have communicated extensively with online are pictured on the left in front of the ISOGG table.

Kalani Mondoy blogs about Polynesian DNA, which is tricky because it is so endogamous. His mother was adopted so he turned to DNA to find her biological family. Richard Weiss is a search angel and adoptee who is involved with DNAadoption.com including the building of their relationship calculator. Each has now found their biological families and both are Mayflower descendants!

Read on for some of my favorite snippets from the conference.
