If people are going to be that way they should,t put their DNA in the data bank.We did the (Y25 and the Y37 test also and the Y25 test with a genetic didtance of 1 lead us right to the name of the man who was on our grpa,s death cert.there was no y37 match.We talked to the people who were also our slaveholders and that,s where we got a lot of information.We were connected by the paper trail that lead through the overseerer that left,with our same last name.There will be quite a few matches with the Y25 test but most of them are distant and the ones with your same last name are closer.That family tree DNA is great.
