Friends of

Below are some sites that are doing excellent work. Each is providing very helpful tools to advance our capabilities in genetic genealogy.

Genetic Affairs

Clustering your matches is one of the most important steps that you can take when using DNA to figure out or corroborate your family tree. Evert-Jan Blom of Genetic Affairs is the original and preeminent creator of AutoClusters. I partnered with Genetic Affairs and provided the probability data for the new AutoKinship tool, which amazingly generates a tree showing the most likely way you’re connected to your DNA matches.

Patricia Coleman Genealogy

The site Patricia Coleman Genealogy is a great site for genetic genealogists to learn how to use the most advanced tools available, including an article on AutoKinship, mentioned above.


I highly recommend subscribing to Louise Coakley’s newsletter at Genie1. That’s where you’ll hear about all of the important news in genetic genealogy. She also wrote a great article on X chromosome inheritance, which would be a good thing to read before diving into the only ranges of shared X-DNA available.

DNA Painter

With my personal family mysteries being pretty far back in my tree, for years I’ve been keeping track of every distinct segment I can identify on both my paternal and maternal chromosome copies. I’ve always done this with text files. But DNA Painter makes it simple and more appealing by giving¬† you wonderful visualizations of your chromosomes and segments. Jonny Perl has also created a very important tool called the Distinct Segment Generator, which will help you take full advantage of siblings’ kits.

Your DNA Family

Your DNA family is a new website that recently launched and will provide you with many features, including for your matches and segment-level data, triangulation, family trees, and collaboration with your matches.


The most advanced peer-reviewed genetic genealogy research in the world is happening at HAPI-DNA.
