TILPACOPAL INDIANS. The Tilpacopal, Pajalat, and Siquipil Indians were three Coahuiltecan bands for whom Nuestra Señora de la Purísima Concepción de Acuña Mission was established at San Antonio in 1731. The aboriginal location of the Tilpacopals remains unknown, but it seems likely that they ranged the area south of the Edwards Plateau.
