In 1835 Slocum revealed to a visitor that she was a white woman who had been captured as a child, and two years later, in September 1837, three of Slocum's siblings came to see her. They confirmed that she was their sister, but Slocum chose to stay with her Miami family in Indiana. Slocum fully assimilated into the Native American culture and was accepted as one of its members. On March 3, 1845, the United States Congress passed the joint resolution that exempted Slocum and twenty-one of her Miami relatives from removal to Kansas Territory. Her Miami relations in Indiana were among the 148 individuals who formed the nucleus of the present-day Miami Nation of Indiana. She is buried at Slocum Cemetery in Wabash County, Indiana. Tributes named in her honor include Indiana's Frances Slocum Trail; the Frances Slocum State Recreation Area on the banks of the Mississinewa Lake near Peru, Indiana; Maconaquah High School in Indiana; Frances Slocum Elementary School in Marion, Indiana; Frances Slocum State Park in Luzerne County, Pennsylvania and Mocanaqua, Pennsylvania.
