Polk was my greatgrandfather, he married Rebecca Pitner 24 June 1869. I'm trying to find his birth father's name. There was a James K. P. Cunningham living with W.A.W Cunningham, 1860 census,Arkansas. As 1870 census Polk was married and not living with W.A.W. who then was living in Polk County,MO
Any help would be great!
