CAGAYA INDIANS. This name occurs in a single Spanish missionary report of 1691, which lists eight groups that lived some eighty leagues southwest of the Hasinai Indians of eastern Texas. The Jumano (Chuman) Indians are named on this list. The Cagayas may be the same as the Caynaayas, named in another document of the same year, along with Jumanos and Cíbolas, as having been seen hunting bison near the Guadalupe River east of San Antonio. If the Cagayas and Caynaayas were the same, then the Cagayas can be identified as Indians of Trans-Pecos Texas, the designated home of the Caynaaya, Cibola, and Jumano Indians.
