AGUIDA INDIANS. In 1683–84 Juan Domínguez de Mendoza led an exploratory expedition from El Paso as far eastward as the junction of the Concho and Colorado rivers east of the site of present San Angelo. In his itinerary he listed the names of thirty-seven Indian groups, including the Aguidas, from whom he expected to receive delegations. Nothing further is known about the Aguidas, who seem to have been one of the many Indian groups of north central Texas that were swept into oblivion by the southward thrust of the Lipan Apache and Comanche Indians in the eighteenth century.
