I am a male. I am the family historian. In an effort to fine-tune my own research into my maternal grandfather's family (the "Jones"), I have my male first cousin take a Y-DNA test, since he has the "Jones" Y-Chromosome (I have my Dad's Y chromosome).
Lo and behold, the test comes back with a perfect match, and a predicted Most Recent Common Ancestor within 3 generations. I have researched back farther than that and I know all of their names. None of the last names match.
My occupation doesn't take me anywhere near genetics... but I am assuming that a Y DNA match with a MRCA that close should have the same surname for his male ancestor, correct? Except if there's been adoption or infidelity or rape, correct?
I sent the results to my cousin, prior to the lightbulb going off over my head. He knows a lot less about this than I do. He hasn't called me yet, but what if he does? Should I just let sleeping dogs lie? Ugh!
