My grandmother was named Retta or Rhetta Barker. She was born in Virginia in about 1909. She lived and died in Tennessee in 1968. I don't know if this is the same person. Based on the year you have listed below, I don't think this is the same person. I have seen a single picture of her, but I don't have any other records of her existence. If she is from the same area or any of this looks like it could actually be the same person, I would love to see your picture and she if she looks similar. I don't have access to the picture I saw in the past.
