Nacao
The Nacao, also called Nacau, were a Caddo people of the Hasinai group in eastern Texas. Their home lay in the wooded country northeast of the Nacogdoche settlements. In 1716 Spanish missionaries founded Nuestra Señora de Guadalupe de los Nacogdoches for both the Nacao and their Nacogdoche neighbors. The Nacao appear only rarely in later accounts and were probably absorbed into the neighboring community. Their country formed part of the wider Hasinai world of the Neches and Angelina river valleys.
