SENCASE INDIANS. In 1737 this otherwise unidentified group of Indians was recorded at San Antonio de Valero Mission in San Antonio. Sencase may be a variant of some other name, possibly Siansi, the name of a Coahuiltecan group at the same mission, but this equivalence cannot be proved. It has also been suggested that Sencase is a badly garbled version of Secmoco, another Coahuiltecan band reported at this mission during the same period. This too lacks proof.
