Welcome to the family tumbleweed! Maggiebelle was my 4th cousin twice removed. My mother is also a direct MILLIKEN descendant on a different branch of the same tree.
Did she and Henry have more than one child? So far, I have only found Elizabeth Ann who graduated from UT in 1944.
Have you ever seen any indicators that originally her name might have been Margaret Belle MILLIKEN (and she just went by Maggiebelle or Maggie Belle all her life)? Her mother was Margaret.
Anyway, you may contact me directly and also view the website at
