I believe we are talking about the same person in Washington Co. Pa., but the William I have shows to be married to Catherine Casner, born 1804. They also show 4 children: Malinda, Andrew, James, and Thomas (My GGfather). I have William's death in Iowa on 26 Feb 1884. We are still not 100% sure, but believe William's father's name to be James or Samuel. Do you have any other info?
