GEDmatch introduces automated tree matching

If you have uploaded your DNA test results to the free GEDmatch site (https://www.gedmatch.com), and included your direct ancestors as a GEDCOM file, you can take advantage of a new feature that is available if you pay $10 dollars to upgrade to Tier 1 membership.

This utility searches the closest DNA matches with GEDCOM trees and compares their trees with yours.

If it finds a MRCA (Most Recent Common Ancestor), it reports it in a table. 

This is the description you will see when you enter your kit number:

This program compares a family tree of the primary kit with the family trees of all of the closest DNA matches that also have family trees. It uses a pretty generous matching algorithm, so please don't take these findings as absolutely proven. It is very possible that this program will, in some cases, wrongly identify common ancestors. So PLEASE do a little bit of follow-up investigation to confirm the findings before accepting them as correct. Hopefully, in time, we will reduce the number of false matches. We feel it's better, for now, to be a little loose in the matching and catch common ancestors with slight variations in spelling and have occasional false matches, than to miss real matches. We hope this allows you to find out how you are related to other GEDmatch users.

I tried it this morning with all of my kits, and it didn't find any new matches for me, but let us know if you have better luck! (Maybe more of your matches will have uploaded trees?)

There is a YouTube video explaining how to use the GEDmatch MRCA Search Tool:

This article is also very helpful, and explains how to download and upload your results:
