Vikky here...Its been a while since we chatted. My hunch is that the Andersons that also settled into Ross co OH...are the same line that connect to the Wilburns and Champs who were in Madison Co KY c 1780...Some of the Wilburn wills of Cumberland, Co KY mention John Anderson and Polly Wilburn Champ...I am wondering if Richard Willborn b c 1717, might not have arrived with these families????
If my other hunches are correct...Then he DID not. I also have some Adams allied with Wallen...and a few other surnames that match with your posting history.
