I am trying to find the 1860 census for Martha A Redmon. I have already found her in 1850, 1870.
Regarding the Benton brothers. I have these as the sons of George S Benton and Catherine:John T --cannot find dates of marriage or death. Probably fought in the Civil War. George Washington Benton who married first Martha A Redmon and then Emma K Cobb Wiggins. Two of her daughters from her first marriage married sons of George Washington Benton. William Franklin Benton (brother of John and George) married a Lou Dicie (maiden name unknown) who MIGHT be a daughter from Martha A Redmon's first marriage. I am looking for evidence of that first marriage for Martha.
Brother James Andrew Jackson Benton is first married to an unknown and has two children Noah and Bamma. His second wife is Mittie M (maiden name unknown).
I don't know what happened to Robert F Benton the youngest brother.
Emma K Cobb Wiggins husband died in 1882,She and George Benton have their first child by 1890. The 1889 death for Martha A makes much more sense.
So do you think Martha's sister Elizabeth is the wife of James Andrew Jackson Benton?
