My great grandparents name's were James Shaughnessy (may have had an O' in front at one time) and Mary (?) McGovern.They settled in Waterveliet, New York.
My grandmother was Alice Veronica b 11-21-1898, she had brothers: John, Thomas, James, who became a priest, Ann, and Mary.I do remember that Ann married someone by the name of Connley (sp) or O'Connelley and lived in or around Troy.
Alice Veronica married Edward George Wallingford of Green Island.They in turn had:Edward Francis, Mary Catherine, James, Elizabeth, Alice; moved to Schenectady and had John (Jack) and Joan.
My mother is Mary Catherine who married John F. Nace.
I have found the Wallingfords and the Nace's.No Shaughessy or O'.Of course there are possibilites that there were other spellings.
