Consanguinity, land inheritance and risk of grandchildlessness

Abstract: Investigating the reproductive consequences of consanguinity in historical Krummhörn, we show social-group specific associations with correlates for fertility and breeding success like the risk of permanent grandchildlessness. While the proportion of mothers, for which not any birth of a grandchild has been documented at all is much lower among socioeconomically privileged farmers, they will even have more often have at least one grandchild born in this population if married consanguineously.
