Hi Linda, The William Keever was probably their son William Keever who was my great, great grandfather. He was born 6 Sep 1805 in Mifflin Co. Pa.and died 8 Feb 1890. He Married an Ann Smith 1 Mar 1827 in Jefferson Co. ,Ohio. John's first wife was Catherine Hawn whom he married about 1804. I had thought Mary Roby was mine but she was John's second wife. Catherine must have died in 1812, probably at or shortly after the birth of Margaret who was born in 1812. I have the three children of John and Catherine as my William, Sarah and Margaret. John and Mary Roby Keever are buried in Morgan Co. Ohio I have been to their graves and also have been to William and Ann's graves, also in Morgan Co. Ohio.
