Kin Groups and Descent. The nuclear family is the most important kin group in Huastecan Nahua communities, but these units are often linked through male and sometimes female ties to form functioning extended families. Descent is determined bilaterally.
Kinship Terminology. Huastecan Nahua kinship terminology has characteristics of both the Hawaiian and Eskimo systems. Parents are distinguished from parents' siblings, and grandparents are distinguished from their siblings, although not according the side of the family to which they belong. Cousins and those married to cousins are in some instances equated with Ego's siblings and their spouses.
