Like the Osage, the Kansa tribe includes a number of families with French surnames. Among them are Pappan, Lessert, Prue, and Roy-names of Frenchmen who married Kansa women in the eighteenth and nineteenth century. The Roys trace their lineage to Michel Roy, who came to live among the Kansa in 1799. One of the Pappan-Roy daughters married an American abolitionist named Curtis while the Kansa were still in Kansas. Their son, Charles Curtis (1860-1936), orphaned at an early age, lived at the Kaw Agency with his grandmother Julie Pappan until she persuaded him to go to his relatives in Topeka. There he received an education, became a lawyer, entered politics, and served Kansas in Congress for 34 years. Curtis sought the presidential nomination in 1928 but lost to Herbert Hoover; Curtis then accepted the second spot on the Republican ticket and served as Hoover's Vice-President from 1929-1933. Some thought Curtis to be a mediocre politician, but Senator William Borah described him as a "great reconciler, a walking political encyclopedia, and one of the best political poker players in America." Ironically, as a Congressman, Curtis was responsible for the Curtis Act of 1898 which helped to weaken and dissolve the Indian Territory tribal governments by subjecting all persons in the territory to federal law, abolishing tribal courts, providing for the survey and incorporation of towns in the territory, and giving all townsmen the right to vote, and setting up free public schools. Thus, the Curtis Act helped pave the way for the demise of Indian Territory and the statehood of Oklahoma.
