Website review: Gedmatch.com

So, you got your DNA tested from Ancestry, Family Tree or 23 & Me. You see your percentages and maybe some distant matches. Is this all there is to it? Not by a long shot. You can request your results and use those resuts on other sites to expand what you know.

One of those sites is Gedmatch and it is a very interesting place to visit. Actually, you need to join and download the information that you will get from Ancestry, or actually any number of other sites which give similar autosomal results. You can also give them your  mito and Y DNA results.

So far I have seen 1500 members who are related within 6.8 generations. I have also seen a much more accurate breakdown of my ethnicity. Instead of saying I have less than 1 % Finnish/Russian it says I am 1.5 % Amerindian which is absolutely correct.

Anyway, if you want to play around with your DNA and maybe find some cousins you never knew you had, this is a good way to do it. It allows you to find the common genes you share and then perhaps to isolate that illusive ancestor.

You need to triangulate your results and at some future point I will talk about how you can actually do this. DNA opens up some new and intersting aspects of genealogy research.
