If you have tested your DNA at Living DNA or uploaded a kit there, you may have wondered how to use the site best. With a much smaller pool of DNA test-takers, you probably don’t have many close matches, and without family trees, it has been difficult to identify common family lines. Two new tools released recently, however, give us more options for discovering and grouping our matches – the chromosome browser and the matchbox,...
Today’s episode of Research Like a Pro is about the second half of Chapter 8 in Research Like a Pro with DNA. This part of the chapter focuses on tools that use segment data to help you find common ancestors with your matches. We discuss chromosome browsers, segment triangulation, chromosome mapping, DNA Painter, visual phasing, and several third party tools. We also review tools to help analyze mitochondrial DNA, Y-DNA, and X-DNA matches. Transcript Nicole...
Have you ever used the MyHeritage chromosome browser to view triangulated segments? It’s a wonderful tool. A member of the Research Like a Pro with DNA study group asked a great question about his experience using it. He said, I’ve compared the DNA of 3 people with my mom: Bob, my mom’s 1st cousin on her dad’s side two DNA cousins I’m researching, Jane and Jill (names changed) Bob triangulates with Jane on chromosome...
Many Americans have been told by relatives that they have Native American ancestry and want to find out if the story is accurate. DNA testing has the capability to help people determine if they inherited any DNA from Native American ancestors. At RootsTech 2020, I attended a class taught by DNA expert Roberta Estes entitled “Native American DNA: Confirming Those Stories.” I am sharing some of the helpful information from Roberta’s class and including links...
Today’s episode of Research Like a Pro is a discussion with Robin Wirthlin about DNA tools and methods involving segment data. AncestryDNA doesn’t provide segment data, but the other companies do! With chromosome browsers and segment data, you can use segment triangulation and chromosome mapping to prove common ancestors. Join us as we talk about how this all works!

Have you heard the term “segment triangulation” associated with DNA and wondered what that meant? Perhaps you wondered if this could help you confirm an ancestor that you’ve researched? Which DNA testing and third-party companies offer this tool? In this article, I’ll define the term and show how the process can help you in your genealogy journey of discovering your genetic family tree. Pedigree Triangulation I previously wrote about pedigree triangulation and used the following visual...
For most of us, the goal of genetic genealogy is to identify how our DNA matches are related to us. We want to determine our common ancestor or identify an ancestor who was previously unknown to us. Chromosome browsers help us do that. By determining that an autosomal DNA segment was inherited from a certain ancestor, we can use that segment information in the future to identify matches whose connection to us is unknown. Chromosome...
