The Fort Parker massacre was an event in May 1836 in which members of the pioneer Parker family were killed in a raid by Native Americans. In this raid, a 9-year old girl, Cynthia Ann Parker, was captured and spent most of the rest of her life with the Comanche, marrying a Chief, Peta Nocona, and giving birth to a son, Quanah Parker, who would become the last Chief of the Comanches. Her brother, John Richard Parker, who was also captured, was ransomed back after six years, but unable to adapt to white society, ran back to the Comanches.
