Ya'ttaish
Yáttaish recalls the Yatasi, a Caddoan people whose villages lay along the Red River in northwestern Louisiana. They were neighbours of the Natchitoches and other Caddo communities, in a country of river bottoms and wooded uplands. In 1686 the French traveller Henri de Tonti visited Yatasi settlements on the Red River. Warfare and disease later reduced their numbers, and Yatasi people joined other Caddo communities near the French trading post at Natchitoches.
