The couple made their home in Wichita, where Elizabeth worked at the American Indian Institute (AII), serving as matron and financial manager. Because Henry had no prior experience teaching, she often served as an advisor and took an active part in running the school for twenty years. Unlike other Native American schools, the curriculum of AII included courses on indigenous cultures, in addition to the academic lessons. Over the next several years, their family grew to include Elizabeth Marion (born 1917), Anne Woesha (born 1918), Lillian Alberta (born 1920), Ramona Clark (born 1922) and Henry Jr. (1926–1929). When Henry Jr. died, they adopted Jay Hunter, a family friend, who was not orphaned, but joined their family as was customary among the Winnebago. In 1931, Henry took a job with the Bureau of Indian Affairs and began traveling as an investigator researching conditions, such as education, health and poverty, among Native American communities. He was often absent from the school and Elizabeth supervised it during those absences. In 1932, she returned to school, taking courses at Wichita University part time, where she eventually earned her bachelor's degree. Henry had been appointed as the superintendent of the Haskell Institute in 1933 and would work in Lawrence for the next two years. Elizabeth resigned from her duties at AII in 1934, but continued to live in Wichita so that the children could finish their schooling and herself took graduate courses at the University of Kansas. In 1937, fire destroyed the school and after struggling to remain open for two years, the decision was made to close the school in 1939. That same year, Elizabeth was asked by President Franklin D. Roosevelt to serve as a delegate to represent minorities for the White House Conference on Children and Youth, examining children and the role of democracy. At the conference, she met Sadie Orr Dunbar, who was the current President of the General Federation of Women's Clubs (GFWC).
