COCOMA INDIANS. The Cocoma (Cocuma) Indians have been identified with the Macocoma, but the identity has yet to be fully demonstrated. When first encountered by the Spanish in 1675, the Cocomas lived in northeastern Coahuila and sometimes ranged northward across the Rio Grande into the southwestern part of the Edwards Plateau in Texas. However, in 1693 the Cocomas were also reported as a tribe that lived between Durango, Mexico, and the site of present Presidio, Texas. It is not certain that these two groups were the same people. The Cocomas of Coahuila and Texas were probably the same as the Macocomas of San Francisco Solano Mission (near the site of present Eagle Pass) and its successor, San Antonio de Valero, at San Antonio. J. R. Swanton evidently considered them to be the same, since he listed the Macocoma as a Coahuiltecan band but omitted the Cocomas from his list.
