I see that my ggg grandfather Uriah Supplee was in Blockley, Philadelphia in the 1820 census. I know he was born in PA abt. 1800 but I didn't know where or who his father was. He moved to Mercer,PA and died there September 05, 1877. It is thought he married a Rachel Stewart 1795-1872 and had Elizabeth, George Rival, Mary Ann and Lydia. Elizabeth married James Zahniser and they were my gg grandparents. Do you have any idea who Uriah's father was? He has been kind of a brick wall for me.
