My wife is a Dufty. Her Great Uncle (Vanrensulaer)was married to Margaret Ellen Fountain daughter of Robert Fountain and Margaret Godfrey. Her Aunt is married to Arthur Fountain son of Fred Warren Fountain, son of Emanuel Fountain who was Robert's younger brother. I have lots of info on her Family.
Are you related to the Burkes from Ingoldsby? My Brother-in-law is married to a Burke.
