I have this "little" bit of info. Phillip Stallman did marry Nancy Haverty who was the daughter of William and Helen O'Connell Haverty. They had four children, William Stallman, David Stallman, then a daughter (name unknown)who married a man by the last name of Gainor, and Henry Stallman. They resided in Roane County, WV. Henry Stallman married Zilpha Riddle.
William Haverty is my 5th great grandfather. He also had a son, Michael H. Haverty who married first Mary "Polly" Stallman (at least we think he married her!) and they had a son, William Henry Haverty who was born in 1822. About 1824 Mary "Polly" Stallman married a man by the name of Connely.
This information came to me from a cousin who did his research in WV. He lives in Mineral Well, WV.
