Walter A. Pumphrey - Texas

I am trying to find out information on my grandfather, Walter A. Pumphrey. The A. could stand for Andrew or Anderson - I'm not sure which. He was born in Alice, TX; his dad's name was W.A. Pumphrey and his mother's name was Beulah Wright; his date of birth was Jan. 3, 1907. If you have any information or know where to lead me next, please respond.
