My g-g-g-g-grandfather was George Mains b. approx 1791 in PA. possibly. His wife was Catherine. I don't know her maiden name but her middle name could have been Hannah or vica-versa. I know George had a son Phillip b. 1816 in Clermont Co., OH. I don't know of any other children to George but perhaps your James H. was a brother. Please reply so that we can share more data. Thank you.
