I also have Mrs. Lou Munday Gray (Tom Hall's sister). Sisters Susan and Martha Munday.
Caroline Younger was married to John Jarrette and her sister Caroline was married to George Clayton. Mrs. Armenia Whitsett Gilvey was a sister to James Simon (Simeon) "Si" Whitsett. I believe (not sure) that Susan Vandiver was a sister to Louis Vandiver. She was a cousin to Cole Younger.
