Last night, I attended a talk of a prominent genealogy speaker. This is a speaker who keynotes conferences and attracts thousands to her talks. Diahan Southard gave her talk “Your Slice of the DNA Pie”, and I watched it on my computer at home. It was a presentation of the Virtual Genealogical Association, ...

In my last blog post, I analyzed my segment matches at 23andMe with Double Match Triangulator,. This time let’s do the same but with my GEDmatch segment matches. Getting Segment Match Data from GEDmatch At GEDmatch you need their Tier 1 services (currently $10 a month) in order to download your segment ...

I am going to show you how I am using Double Match Triangulator, and some of the information it provides, at least for me. My own DNA match data is difficult to analyze. I come from a very endogamous population on all my sides that originates in Romania and Ukraine. The endogamy gives me many more matches than ...

I’m working on a series of articles to show how I am using the new 3.0 version of Double Match Triangulator to analyze my own segment match data. As much as I’d like you to believe that I’ve developed DMT for the good of genetic genealogists everywhere, I humbly admit that I actually developed it so ...

It’s been 35 years since GEDCOM 1.0 was released to the genealogical software development community in 1984. It’s been 20 years since GEDCOM 5.5.1, the last official specification by FamilySearch was released on October 2, 1999. Five days ago, October 2, 2019, the gedcom.org website was renewed containing ...

I’m cleaning up my directories after over 3 years of development of Double Match Triangulator. When I released Version 1 of DMT back in August 2016, I had it write information about the run to a log file, primarily so that I could debug what was going on. But I realized it is useful for the user as it could ...

After 10 months of hard work, I have finally released DMT 3.0. You can download it from www.doublematchtriangulator.com. (It is a Windows program. My apologies to Mac or Unix users) All purchasers of DMT get a lifetime license. All updates including this one are free for past purchasers. There’s ...

Someone on Facebook reported a new feature at 23andMe and I couldn’t wait to try it. This 23andMe beta “auto-builds”  your family tree from your DNA connections with other customers. They aren’t the first to try something like this. Ancestry DNA has ThruLines, which uses your tree and your DNA ...

There’s a bad rumor going around that segment matches, especially for small segments, can be very old. I’ve heard expectations that the segment might come from a common ancestor 20 generations back or even 30, 40 or more. And that’s said to happen even if you have a fairly large 15 cM segment. Part of ...

This is my first blog post in over 2 months. The reason is that I have been working very hard trying to finish Version 3 of Double Match Triangulator. Every thing I’ve been doing with it is experimental, and there’s no model to follow. So it’s tough to get it just right. I started the documentation of the ...
