The wife of Valentine was Frances Branham, proven by the permission slip for their daughter Rhoda to marry.
Frances Baskett was the wife of David Branham, Sr. and mother of Valentine's wife.
As far as I know the name of the first wife of Blackburn Akers, Sr. has not been determined. She was probably the daughter of John Blackburn and her name could be Elizabeth just as well as Susannah. If anybody has proof of her name I'd appreciate knowing.
