My ggrandfather was Isaac Postlewait, b. Greene Co., Pa. in 1815. He m. Mary Ann Haught. Their children were Uriah P., Elizabeth, William, Suzannah, Sarah, Joseph J., Elijah, Nancy S. and He married a second time to Nancy Anderson Grady. Their children were Christine, John B., Mary Jane, E.J., Thomas, Andrew Clay and Mary. Isaac's father was ISAAC A. POSTLETHWAIT. At one point he was listed as Isaac's father when Isaac and Nancy Grady were married in Pleasants County, W.Va. on April 7,1860. I'm trying to locate whom he married, his children and who his ancestors were. I'm sure they came from Lancaster, Pa. Any help would be greatly appreciated. The spelling of Postlethwait has changed over the years.
