Re: EDGAR/CLARK OF PA
My records show that Polly Edgar, b. abt. 1820 married John Clark in Green County, Kentucky on August 12, 1839.
Polly was the daughter of Josiah Jefferson Edgar b. Sept. 17, 1789 in Logan County, KY and b. abt. 1790 in Logan County, KY.
FYI - this comes from County marriage records, I know the names don't match exactly but it may be helpful.Josiah had 6 daughters by three different marriages, however all but Polly's older sister Betsy were too young to be matches to your ancestor.
I have spouses for all of the daughters except Betsy.
