By the early 1950s, Palmer had married Rev. Lee Chupco and was speaking on behalf of the Methodist church of the work that she and her husband did among Oklahoma's Indian tribes. Rev. Chupco was the superintendent of the central district for Indian Missions and both he and his wife traveled the country on speaking engagements. In 1950, Chupco was elected to serve as president of the Women's Society of Christian Service for the
United Methodist Church's Oklahoma Indian Mission. She held the office until 1954 and then was re-elected to the post in 1958, serving through 1960. Chupco was one of the co-founders of the Tulsa Indian Center, which was created with funds from the
Department of Health, Education and Welfare as a counseling center to assist
Native American peoples in making the adjustment to living in urban environments. In 1970, Chupco was one of the members of a watchdog committee appointed by the Oklahoma Indian Rights Association to monitor civil rights violations of Native Americans in the state. She was elected to the board of
Church Women United in 1971, as one of twelve vice presidents and one of only four Native American members. The three-year term was historic as it was the first time an African American woman had been elected to the presidency. When the
Muscogee (Creek) Nation re-established its government in the 1970s, Chupco was selected as one of the first women to serve on the Muscogee National Council. She served for twenty-three years, as a tribal councilwoman. In 1984, Chupco was elected as treasurer of the Oklahoma Federation of Indian Women. In 1992, Chupco was recognized by the
Oklahoma State Senate for her tribal leadership. ==Death and legacy==
