 The most prominent division, between Northern Cochimí and Southern Cochimí, has generally been put to the south of San Ignacio (Mixco 1978, 1979, 2006; Laylander 1997).At one time designated "Peninsular Yuman", Cochimí bears an evident relationship to the Yuman languages of northern Baja California, southern California, and western Arizona.Mauricio J. Mixco (1978, 2006) reassessed this relationship and judged it to be too distant for Cochimí to be included within the Yuman family proper.
