I am trying to locate info on my great aunt and her amily. They are listed in the 1900 Quapaw Nation census with their ward, Pearl Spybeck. CW is listed as a physician. In the 1920 census they are listed in Delaware county, Oklahoma. I don't find them on the 1930 census. Odelia was alive and listed on an obit in 1921. Interested in any info I can find on them, particularly death and burial location. Any help will be appreciated.
