What is GEDMatch?

The name GEDMatch was coined from a combination of “GED”, which represents the universal standard for the exchange of genealogical data, GEDCOM, and the “match”, because it helps users find and connect with people share varying portions of their DNA.


How Do I Use GEDMatch?

Using GEDMatch is as simple as inputting the results of your DNA test from either FamilyFinder, 23andMe, or AncestryDNA.

We mentioned a few paragraphs back that the GED part of GEDMatch comes from the use of GEDCOM.

GEDCOM allows you to extract the genetic information that you received from your previous ancestry DNA test and explore relatives from companies other than the one you got your initial test done from.

For example, if you have done your initial ancestry genetic test from 23andMe, you can explore DNA matches from the Ancestry DNA database through GEDMatch. This effectively helps you avoid paying for the same test twice.

If that’s not enough reason to convince you to give it a try, then there’s this: GEDMatch helps you identify exactly where you match with your relatives, helps you discover your trace ethnicity, provides email addresses for easy contact with your relatives,

And most of all, searches results from pretty much all existing DNA databases in order to find a match for you.
