Mary was my mother as well as my twin brother Jerry. I am the only surviving sibling born to her. I knew GB was born Masterson and changed to Gilliam. I do not have any info on Masterson. I was told Mary left Gilliam because he was mean and beat her..a lot. I do not believe Mary and Thacker were ever married and she died shortly after my twin and I were born. Thacker married again thirty days after my mothers death. There was a daughter born five years later from that union. I found her through this web site about ten years ago and we remain close. I also found an older brother from Thacker's first wife born in1930. Thacker never stuck around after there were children born. I feel he probably has other children from various unions around the country and I would like to find them somehow. I am sorry I do not have any info to help you with your search.
