The Algonquian family includes several languages in North America (Canada, U.S.A. and Mexico), such as Cheyenne, Arapaho, Cree, Ojibwa, and Fox. Since it has been connected historically with some non-Algonquian languages in North America, it is part of a larger family, the Algic stock.
Kickapoo is the only language from this family that is spoken in Mexico, in the state of Coahuila. It is closely related to a larger group of the same name in the state of Oklahoma, USA. Speakers of this language group arrived in Mexico in 1839.
