I am searching for my grandparents on my mother's side. I have her death certificate but apparently my father was not able to give her mother or father's name. My mother's name was Betty Susan Cox and was born on June 25, 1916 in Arkansas. Married my father in approx. 1933 and my Mother died at the age of 40 in Harris coo, Houston, Texas in 1957. She had a sister named Wyonna Cox Jones who is now deceased. I am trying to locate my grandparents and have almost reached a dead end. My Mother also had a brother named Orville and one name Ivey Cox.. whereabouts unknown. Any help would be appreciated... Thank you
