The Tequistlatecan languages are part the proposed Hokan family, but are often considered to be distinct family. Campbell and Oltrogge (1980) proposed that the Tequistlatecan languages may be related to Jicaquean (see Tolatecan), but this hypothesis has not been generally accepted.

The Oto-Manguean family has existed in southern Mexico at least since 2000 BCE and probably several thousand years before,some estimates using the controversial method of glottochronology suggest an approximate splitting date of Proto-Otomanguean at ca. 4400 BCE.

Mexican Indigenous Languages -> Language Isolate -> Seri
The term Serian family may be used to refer to a language family with Seri as its only living member; related languages have disappeared in the last couple of centuries.
Attempts have been made to link it to the Yuman family, to the now-extinct Salinan language of California, and to the much larger hypothetical Hokan family.
