I am looking for info on John T. Hamaker and wife Gertrude "Gertie" (Munday). They are in the 1920 census in Poteau, Le Flore Co., Oklahoma and in the 1930 census in Muskogee city, Oklahoma. I think that John T. is the son of Samuel and Clarissa Hamaker who are in the 1880 census in St. Joseph, Buchanan Co., Missouri. John T. was born about 1871 in Missouri.
John T. was Gertrude's second marriage. Her first marriage was to Henry L. Reidling, and they resided for a time in St. Louis prior to about 1900.
