Looking for the bible of Joseph McMAHAN and his wife Mary Elizabeth (Schryhauser) McMAHAN married Pittsburgh, PA 1792, living in Adams Co, OH 1820s, Whiteside Co, IL 1830s. Bible was said to be in the possession of their son Gregory McMAHAN in 1840s living near St. Louis, MO (riverboat captain). Hoping someone has come across this Bible some place... Penny
