SIANSI INDIANS. In the early eighteenth century the Siansi Indians, who appear to have spoken a Coahuiltecan language, were reported at San Francisco Solano Mission (south of the Rio Grande near the site of future Eagle Pass). When this mission was moved to San Antonio and became known as San Antonio de Valero Mission, the Siansis moved with it. It has been suggested that Siansi and Sencase are variants of the name Secmoco, but this has not been proved.
