Seneca diplomat Cornplanter, who had aided in negotiations with the United States representatives, was later granted an additional 1500-acre plot in Pennsylvania by that state legislature as personal property for him and his descendants. Mary Jemison, a European-American woman who had been taken captive and assimilated into the Seneca tribe, was also granted land but sold her plot a few years later and established Jemison Town on the Allegany Reservation. Many Seneca moved to Canada, settling with other Iroquois at the Six Nations Grand River Reserve in what is now Ontario.
