Who is Mary Jemison from The World Turned Upside Down: Indian Voices from Early America and what is their importance?

Mary Jemison was a white European who enjoyed a typical colonist's life until she was abducted by Iroquois Indians at age fifteen in 1758. She was smuggled to the Seneca tribe in western New York, which was known as Genesee country. Thereafter, she became known as the "White Woman of the Genesee." In a ritual, she was accepted into the clan and treated as a family member. She later learned that she was abducted in order to replace a dead relative.
