I'm looking for any information on my grandfather's family. His name is William Coley Davis and he was born on 9 November 1904 in Mount Pleasant, Texas. He married Symka Tebben on 4 July 1950. They had two children. He died on 10 April 1989 in Phoenix, Arizona. I have very little information on his family--not even his mother's name. Any help on this would be much appreciated. Thanks.
