Believe it or not I think I just figured it out! It appears that Martha A Redmon was first married to Jeremiah Meek who was either killed or died in the Civil War. He is buried in Georgia. Now I just have to get a copy of the pension request she filed and see if it has Redmon as her maiden name! The ages of the two children she had with Jeremiah matches up with the two "Benton" girls in 1870 who are too old to be Bentons!
