Your grandfather Harden Smith Mawyer was the third child of Thomas W. Mawyer Jr. born 1855 and Bettie Kirby. Thomas W. Jr. was the fifth child of thirteen children born to Thomas W. Mawyer Sr. and Rhoda Ann Critzer. Thomas W. Sr. was born 1823 and Rhoda Ann was born 1827. They lived just north of Covesville Va. on what was then the Boaz Farm. If I can be of any other help let me know.
