On my Y-DNA Ancestral Origins page, why are so many different countries listed?
When you have one of the more common Western European Y-chromosome DNA STR (short tandem repeat) haplotypes, the results will include matches from many European countries on your Y-DNA Ancestral Origins page. This happens most often at the Y-DNA12 level of testing. As at this level your matches may date to a common ancestor several thousands of years in the past, the DNA signature has had time to spread throughout a large region or a continent during historic migration events. Testing additional markers by upgrading to the Y-DNA37, Y-DNA67, or Y-DNA111 test will confine your matches to those who are more recently related. This will also reduce the number of locations to those that are relevant. Note: As the Y-DNA111 is a new test, relevant matches will not be available at first.
