I don't know anything about the Kerseys, but I have Wallaces on my line, and
wonder if your John O. and Edward O. have any relationship to the Jane
Wallace of Bourbon County, KY, who married David McKee in 1794. Jane was
born in Bucks County, PA, 1767. She was the youngest in a large family.
Father was Joseph Wallace. Among her brothers were two who fought in the
Revolutionary War, John and Andrew. The Wallaces went from Bucks County to
what is now Loudon County, VA, shortly after the Revolution, and then on to
Fayette County, KY, around 1790.
David and Jane McKee lived in Harrison County, KY, most of their married life
(both died in 1844). Two daughters and a son married and moved to Decatur
County, IN, by the 1830s.
