I have not abandoned this possibility.I have visited Wayne Co. KY. (actually the town is Monticello, KY.) I noticed the John you speak of who married Polly Long.Interestingly, the marriage was short lived and John left town "in a hurry." There is also a Bartleson private cemetary in Monticello which has Bartleson's back to 1700's. I, like you, surmised John went west into Ohio where he met Mary Wilson Chapman (born 1809).Our family history throws a wrench in the works here. You said that Mary Chapman was a widower. Our records indicate she married John in 1825 which would make her 16. If that is true, I doubt she could have been a widower. Our family historian, Marvin Layman, discounts the Kentucky Bartleson link.I am on the fence. Any help you can be would be appreciated.
