I am trying to figure out who my ggg grandfathers parents were. I now know that he was born in Jefferson County, Ohio on September 26, 1831. Can anyone help me out with this? I believe that his parents were both born in PA by what is in later census records. I have not located him in the 1850 census, I believe that he was still living with his parents at that time. His name is Harvey E. McMillin (spelled various ways.) Thanks. Jennifer Smith
