O'Fannie St. John Nix married John Judge Hightower, Jr. They had two children John Judge Hightower III and Milton Graham Hightower. I believe these two brothers owned the Hightower Brothers Livery Stable.
My mother's half-sister, Eleanor Inez Hunt, spent summers with Milton's children who were her 2nd cousins. This was apparently notes from some of Eleanor's homework about Edgar Allen Poe.
