I'm looking for info on my great great great grandmother, Mary Auville, who went by the name of Polly. I don't know when or where she was born, but it would have to be around 1820 or so, and probably in northern West Virginia, southwestern Pennsylvania, or western Maryland. She was married to John F. Armstrong (about whom I also do not know anything). Their daughter, Sarah Ann Armstrong was born 3 July 1841 and died 29 Jan 1888. Sarah Armstrong was married to George Washington Deahl, a Civil War veteran. Any information about Mary Auville's family would be greatly appreciated.
