I am trying to locate information about Mary Marshall, who married Andrew Kells. She was born in PA and died in 1843 In Guernsey Co. I believe they were married in PA, but moved to Ohio in 1812-14. Andrew Kells died in 1858 in Guernsey Co. and his Will was witnessed by Robert Marshall and John R. Marshall. I feel there is a connection there, but can't find it. Theda Kells Hoyt
