HAESER INDIANS. The Haeser (Saesse, Siaexer, Xaeser) Indians were Coahuiltecan-speaking Indians who, in the seventeenth century, ranged from northeastern Coahuila northward across the Rio Grande to the southwestern portion of the Edwards Plateau, particularly in the area of present Kinney County. Like other Indians of northeastern Coahuila at this time, the Haesers crossed the Rio Grande to hunt bison.
