give up their lands to the United States. In 1797 the Seneca sold much of their land at Little Beard's Town to Americans. At that time, during negotiations with the Holland Land Company held at Geneseo, New York, Mary Jemison proved to be an able negotiator for the Seneca tribe. She helped win more favorable terms for surrendering their rights to the land at the Treaty of Big Tree (1797). Late in life, Jemison told her story to the minister James E. Seaver, who published it as Narrative of the Life of Mrs. Mary Jemison (1824; latest ed. 1967). It is considered a classic captivity narrative. Although some early readers thought that Seaver must have imposed his own beliefs, since the late 20th century, many history scholars have thought the memoir is a reasonably accurate account of Jemison's life story and attitude. When she was given her liberty, she decided to stay with the Senecas, because her eldest, warrior son was not allowed to go with her and, mostly, she feared her relatives "... would despise [my Indian children] if not myself; and treat us as enemies; or, at least with a degree of cold indifference, which I though I could not endure." In 1823, the Seneca sold most of their remaining land in that area, except for a tract of land reserved for Jemison's use. Known by local European-American residents as the "White Woman of the Genesee", Jemison lived on the tract for several years. In 1831 she sold it and moved to the Buffalo Creek Reservation, where some Seneca lived (others had gone to Ontario, Canada). Jemison died on September 19, 1833, aged 90. She was initially buried on the Buffalo Creek Reservation. Jemison's heirs later changed their surname to "Jimerson" and established the community of Jimersontown on the Allegany Indian Reservation. Mary's account of her capture "The party that took us consisted of six Indians and four Frenchmen, who immediately commenced plundering, as I just observed, and took what they considered most valuable; consisting principally of bread, meal, and meat. Having taken as much provision as they could carry, they set out with their prisoners in great haste, for fear of detection, and soon entered the woods. On our march that day, an Indian went behind us with a whip, with which he frequently lashed the children, to make them keep up. In this manner we traveled
