Walter A. Cox changed his name to William A. Cook around 1939. Walter/william may have been Cherokee moving through the Eldon, MO area at the time of his birth. He was in WW1 with the 130th machinegun Battalion Company C. He died July 26, 1958. He married Cecil (Cecile, Cecilia) Philpot in 1928. We have a copy of the original marriage certificate. My Grandmother may have been adopted by the Philpots. My daughter and I have check with the military, national guard, Trustees of deeds, Museums, newspapers, obituary's and Churches on both of my grandparents.
