CASO INDIANS. The Caso Indians are known from a Spanish document of 1748 that lists the names of twenty-five Indian groups of east central and southeastern Texas who had asked for missions in the general area. Although it cannot be demonstrated, it seems likely that the Casos were the same as the Caxos, who were reported in a Spanish missionary report from eastern Texas in 1691. The Caxos are generally considered to have been Caddoans of the southwestern or Hasinai division.
