Doustioni—
A small tribe living near Natchitoches, Louisiana. They also appeared in European accounts under the names of Souchitiony, Dubchinsis, and Oulchionis.
In 1702 a crop failure caused the Indian agent St. Denis to move their neighbors, the Natchitoches tribes, from the Red River to an area beside the Acolapissa on Lake Ponchartrain. The Doustioni however, chose to remain in their country and reverted for a time to hunting rather than move to the Lake Ponchartrain area.
In 1714 when St. Denis brought the Natchitoches back and started an establishment among them the Doustioni accepted an invitation to settle close by the post. In 1719 they were known to be living on an island in the Red River not far away. Since nothing more was written about them, they probably lost their identity in the Natchitoches tribe.
Nasoni (Nissohone or Nisione)—
This tribe appears in 1542 as a “province” entered by the Spaniards during an attempt by DeSoto’s expedition to reach Mexico by land. It was southwest of the present city of Shreveport. They were poor and had very little corn. In 1687 there were 2 Nasoni towns, an upper town and a lower one. The latter was 27 miles north of Nacogdoches, Texas and Upper Nasoni was near Red River just south of the river.
Tribal wars with the Osage Indians and disease left their villages destroyed and abandoned. By the close of the 18th century they had disappeared, or merged with the Kadohadacho.
Natasi—
A Caddo tribe on Red River between Natchitoches and Shreveport mentioned by writers between 1690-1719. It was probably part of the Yatasi.
Their villages were destroyed and abandoned due to tribal wars and disease and by the close of the 18th century they also had disappeared.
