Who the Wife of William Ringo

The Ringo Family History reflects William Ringo, born 1-13-1781 in Loudoun County, Va, the son of Philip Ringo and Margaret (Peggy)Lewis. In 1805 he was married, but his wife's name s not recorded. We don't even know her first name, let alone her maiden name. She and William Ringo had seven children, all of which have complete histories and genealogy recorded in the Ringo Family History. Sure is frustrating having my complete genealogy back to 1615, but not knowing my 3 times great grandmother's name or anything about her.
