I am relatively new to Ancestry.com, but I have reason to believe that I am also a great-great grandson of Josiah Bodkin. I believe my line runs Josiah - John E - Cora Lee Bodkin McCoy - Leonard McCoy - Me. The records are kind of thin as my dads generation is all gone now, so there really aren't many people to talk to. John, Cora and Leonard would have spent time in the Malden (Charleston) WV area.
If we are talking about the same Josiah (b 1826?), I have found a few possible leads, but I don't really know how valid they are.
I was hoping that you would be willing to exchange a couple of messages to confirm what I think I am finding. I will share whatever I have found.
