FTDNA and was excited to find that FTDNA says we are fourth cousins. His father was adopted and he believes us to be related on his father's side. If I only knew who all my 3rd great grandparents were, we might unlock the mystery of his father's heritage!
Unfortunately, he and I are genetically related on a branch of my family tree that I know very little of. Or should I say, that while I know we are related on my father's side, he and I are NOT related on the branches of my family tree that I have identified MRCA genetics on or that I know a great deal about through research. So I don't have fairy tale story of unlocking the family mysteries of my adopted 4th cousin once removed (even were the FTDNA estimate to be accurate, which is another post altogether, I'm sure). But I do have a fairy tale about how freakin' easy it was to get a list of my 3rd great grandparents.
