I have found information on other family tree(s) that my mother, Mildred Doris (Carlton) Gray was the daughter of Frederick Lee Carlton and Thelma Warren Carlton. I knew my Mom's mother to be Bertha V. (Davis) Carlton. Bertha was married to Frederick Lee Carlton on the 1930 U.S. Census and they had a daughter Ruby VIrginia (Carlton) Estes. Mildred Doris was listed as Ruby's half-sister.
I have also seen my mother's name listed as Mildredge or Mildridge and without the middle name Doris. Any assistance would be appreciated. My personal contact is onebeforejesus at y a h o o.
