Gurgy ‘les Noisats’, a burial site in the Cerny cultural horizon 11 without any monumental architecture, is located close to a dozen contemporaneous monumental sites (in a radius of 100 km Supplementary Note 1 and Supplementary Fig. The Paris Basin during the Middle Neolithic (around 4700–4300 bc) is well-known for the emergence of the monumental funerary architectural structures of the Passy phenomenon 10 dedicated to select individuals from Neolithic communities. Studies on biological relatedness in the European Neolithic are still rare and to date have focussed only on groups from specific funerary contexts such as megaliths 6, 7, 8, which typically cover high-status groups or individuals, or mass graves 9, but have not included non-specific graveyards that may be more representative of the general population. Combined with evidence from archaeological, anthropological and isotopic records, information on the biological ties between individuals can provide a background against which basic elements of social relationships (kinship organization, residence or migration patterns) can be inferred or ruled out.

With the optimization of ancient DNA (aDNA) methods, it is now feasible to obtain genome-wide data and reconstruct precise genetic relationships between individuals buried at the same site. Kinship and biological relatedness are difficult to assess in prehistoric societies. Age-structure differences and strontium isotope results by generation indicate that the site was used for just a few decades, providing new insights into shifting sedentary farming practices during the European Neolithic.

The absence of half-siblings and the high number of adult full siblings suggest that there were stable health conditions and a supportive social network, facilitating high fertility and low mortality 5. The microdemographic structure of individuals linked and unlinked to the pedigrees reveals additional information about the social structure, living conditions and site occupation. We find that this burial community was genetically connected by two main pedigrees, spanning seven generations, that were patrilocal and patrilineal, with evidence for female exogamy and exchange with genetically close neighbouring groups. Here we report ancient DNA, strontium isotope and contextual data from more than 100 individuals from the site Gurgy ‘les Noisats’ (France), dated to the western European Neolithic around 4850–4500 bc. Stable isotope data, sex and age at death can provide insights into the demographic structure of a burial community and identify local versus non-local childhood signatures, archaeogenetic data can reconstruct the biological relationships between individuals, which enables the reconstruction of pedigrees, and combined evidence informs on kinship practices and residence patterns in prehistoric societies. However, for prehistoric societies, these systems can be studied only indirectly from biological and cultural remains. Social anthropology and ethnographic studies have described kinship systems and networks of contact and exchange in extant populations 1, 2, 3, 4.
