JEMISON, Mary (or DEHEWAMIS), born at sea in 1742 or 1743; died on Buffalo creek reservation, 19 September, 1833. She was the fourth child of Thomas Jemison and Jane Irwin, who left Ireland for Philadelphia prior to her birth. The family settled near Marsh creek, on the frontier of Pennsylvania, and there followed a farming life until the spring of 1755, when they were captured by the Indians. The elder members of the family were killed, but Mary's life was spared, and she was adopted into one of the tribes of the Senecas. A few years afterward she married Shenijee, who treated her with kindness, and by whom she had two children. In 1759 she went to live with her Indian mother at Little Beard's town, on the banks of the Genesee river, and there spent the remaining seventy-two years of her life. Her first husband died soon after her removal to New. York, and, after three years, she married Itiokatoo. Thenceforth she remained with the tribe into which she had been adopted, acquired in her own right a large amount of property, and was naturalized in 1817. She was the mother of eight children. In 1831 she removed to the Buffalo creek reservation, and in the summer of 1833, a few months prior to her death, adopted the Christian faith. She was widen known as "the white woman."
