Looking for the connection between William A. W. Cunningham and Elizabeth Clark. My great grandfather was James Knox Polk Cunningham. Story has it he was born a Clark about 1851, Kentucky. Found a James K. Cunningham living with William A. W. Cunningham in Carroll Co. Arkansas. 1860 census. When W.A.W. and family moved to Polk Co. Missouri, 1870 census, James K. was not listed. He marriedl Rebecca Pitner 1869 in Polk Co, Missouri.
Thanks for any help/hints to my brick wall.
