Hello Lisa According to Heritage of Walker County Alabama, Ruben Keeton married Mary Townley. She was daughter of Henry Townley and 1st wife Agnes Rich. Ruben was son of William and Catherine Keeton. Ruben was born abt 1787 in SC. He married Mary 1818 and moved to Alabama in 1819. Ruben and Mary's children were William, Rhoda, Seraphina, Archibald, Ruben Jr., and Meriam.
Archibald, Ruben and Mary's son born 20 Nov. 1827 married abt 1851 to Martha Jane Staggs. She was daughter of John and Martha (Rutledge) Staggs. I thinks he was named after Ruben's brother Arichbald (my line). Archibald and Martha's children were Isham (I think this is your line), Benjamin, Martha, Catherine, Rhonda, Susan, Arichbald F. and Kitty.
