Hi: I am researching a group of four brothers and their brother-in-law who emmigrated to Columbiana Co, Oh 1804-1807. Their names were William, James, Jeremiah and Jesse Callahan and their Brother-in-law, Elias Adgate. An old history of Columbiana Co, described them as coming from "Redstone, Pennsylvania". An old gazette shows two Redstones, one in Fayette Co and one in Beaver Co. I cannot find any current map listing in Beaver co. Does anyone know if there was a Redstone in this county? Where was it? Has anyone heard of this family? Thanks. Deborah Ann Arbor, MI
