My daughters' and their father descend from George Nixon and his first wife Mary Combs through their son Jonah Nixon/Elizabeth Titus and have matched their DNA on Ancestry.com. Years ago when I first started working on genealogy I found a massage on rootsweb about a Mary Nixon being found hanging in the barn. George Nixon's second wife was Mary Gregg Nixon. Does anyone know if it was Mary Combs Nixon or his second wife Mary Gregg Nixon? The message is no longer on rootsweb.com. Thank you for your help.
