I have discovered that the Robert Ragin who married Mary Richardson was probably born about 1906, not in the late 1800s as I previously stated. There is a Robert Ragin, age 24, on the 1930 census record living with his wife, Mary, and sister-in-law Susan Richardson. This could be the Robert I am searching for.
Additionally, I have a note in my file that Robert Ragin was born Aaron [or Jaron] Ragin.
I can't be certain of the validity of this information since the source of the information has given me name changes for three family members so far. Moutrene Ragin's given name is said to have been 'Eartha' before she changed it. Robert Ragin's given name is said to have been 'Aaron' or 'Jaron' before he changed it.
Additionally, this individual says that Moutrene's husband, John Franklin Patterson, also had a previous name.
If anyone recognizes the names 'Eartha', 'Aaron', or 'Jaron', please let me know.
