Network of kins. The subnetworks represent patterns of connection between individuals who are horizontal kin and are extracted from the network of families illustrated in Fig. 5. Each node in the above subgraphs is an individual (offspring) resulting from a link (parental union) in the subnetworks in Fig. 5. The colour of a node represents the birth region of the individual. The colour of a link indicates the nature of kinship—magenta: half siblings, blue: first-cousins, violet: first-cousins-once-removed, green: half-first-cousins, red: second-cousins. We denote the kin network corresponding to the core of the LCC as Core-LCC-kin, that corresponding to the core of first of the second largest connected components as Core-SLCC-a-kin, the kin network corresponding to the core of the other second largest connected component as Core-SLCC-b-kin, and the core for the third largest connected component as Core-TLCC-kin. The characterization of these subgraphs in terms of the usual topological parameters is provided in Table 1
