Looking for siblings/parents of William Marion Davis 3/2/1876-1953. According to death cert. he was born in Douglas Co., MO and his father's name was George. He married Margaret C. Boothe of Taney Co in about 1905 and their first child, George C., was born in Arkansas in 1906. They are in Barry Co, MO in 1910, and then OK and TX until William's death in 1953. Any leads greatly appreciated.
