SABEATA, JUAN (?–?). Juan Sabeata, Indian chief, was born in New Mexico and became a chief of the Jumanos near the mouth of the Río Conchos in Chihuahua. He was given the name Juan when he was baptized at Parral. His stories of the “great kingdom of the Tejas” were responsible for the expedition of Juan Domínguez de Mendoza in 1683–84. In 1691 Sabeata was on a hunt on the Guadalupe River and asked Fray Damián Massanet for more missionaries for the Jumanos.
