I have a problem I am suppose to be related to William Rufus devane King through my greatgrand mother it seems her great grandfather William Vann married a Mary King sister of William Rufus devane King (vice President) But I cant find anything about a sister named Mary. Can anyone help me. Also I find conflicting reports on Williams parents one I have his parents as William King and Margaret Devane other ones say his father was a Michael King. Really confused Thank You in advance for your help Bpearce265@aol.com
