Tamyen (also called Santa Clara Costanoan) has been extended to mean the Santa Clara Valley Indians, as well as for the language they spoke. Tamyen is listed as one of the Costanoan language dialects in the Utian family. It was the primary language that Natives spoke at the first and second Mission Santa Clara (both founded in 1777). Linguistically, it is thought that Chochenyo, Tamyen and Ramaytush were close dialects of a single language.
