  • Y Match and FF

    If a person is in my Y list 25 with a gd of 2, and he is also in my Family Finder list, would this mean that he is from the paternal side?

    The short answer is no. The tests are different. Family Finder will give you matches to either lineage and unless this is a close match both in YDNA and in Family Finder there is not even a good probability they are of the same line. Had you asked if a YDNA match of 67-2 markers who also had a "Close" Family Finder prediction (like a 3rd cousin) is related to your father's lineage the answer would be much a more probable "yes" than in this case. Still no guarantee though, just more probable.

    This person and you may have a distant YDNA relative from many generations ago yet this person may be related to you through your mother's family in a closer time frame than the YDNA match.

    In this case there is no way to tell unless you have a paper trail or other data to use in backing the connection up. A YDNA 25-2 could end up being a either distant or very far. If you have not tested more YDNA markers it might be a good idea to see if the match continues past 25. It would also be a good idea to see if this one Family Finder match has other people in common with you who would help you confirm it is a paternal and not maternal match.

    There are just too many variables at this point.

      Thanks Matt. When the paternal surname is unknown you are hoping for even a far off connection. Just to be able to say someone is related on the paternal side even if you have no idea how, is a small miracle. Still waiting for a 37/37 match and plugging away on ff.
