I have an Arrenah Isenhauer born 1790 in Lincoln Co., NC, who married John Wike. I have Mary Isenhour born 1787 in Lincoln Co., NC, who married Barnett Fulbright. Arrenah and John Wike's son, Andrew, married Mary and Barnett Fulbright's daughter, Mariah. Does anyone know if Arrenah and Mary are sisters? And who their parents might be?
