I am hoping that this is not too basic a question for this group. During my research of my dad’s family, I discovered that my dad’s father’s father (my dad’s grandfather) was adopted at birth by his mothers husband and given his mothers husband name. What this means to me is my great grandfather’s ancestors need to be found. My question is what do I need to do to discover who this man is. My brother did a Y-DNA through family tree DNA and has 3 matches – One of them is that a genetic distance of 2 and the other 2 are at a genetic distance of 7. None of them have my brothers surname and so far we have not figured out a match that would give us our paternal great grandfather. Through ancestry DNA there are possibly a few matches that I do not know where the connection is so one of these could be a descendent of a common ancestor as I mentioned so far I can’t figure it out. If anyone has any suggestions on how I can maneuver through all the places we have DNA to figure this out I would appreciate it. I have tested at ancestry DNA and family tree DNA and 23 and me and have uploaded raw data to GEDmatch and my heritage. Any help is appreciated, Gail Jorgensen
