• Paquimé (also known as Casas Grandes), situated in northern Chihuahua between Mesoamerican and Ancestral Puebloan groups, was a vibrant multicultural centre during the thirteenth and fourteenth centuries AD. Substantial debate surrounds the social organisation of Paquimé's inhabitants. Here, the authors report on the analysis of ancient DNA from a unique child burial beneath a central support post of a room in the House of the Well. They argue that the close genetic relationship of the child's parents, revealed through this analysis, and the special depositional context of the burial reflect one family's attempts to consolidate and legitimise their social standing in this ancient community.
