Hello, I am researching John (Campbell?) Carr/Karr/Kerr (wife Jane Rolston/Ralston), father of Hiram Carr, believed to be from Mercer County Pa. pre 1825. John's father believed to be William (wife Nancy ?) and a brother David, possibly a sister Nancy (husband David Drake). They show up in Columbiana County, Ohio, William 1830, William/David/John in 1840. Any info or how I could get census//birth/marrige data would be greatly appreciated. Ray
