Many studies on family solidarity emphasize the importance of norms for understanding
why people help family members. The question of where kinship norms come from, however, is underanalyzed. This study examines the influence of the family of origin on the
development of kinship norms using models of sibling resemblance estimated on a
large-scale multi-actor survey. Analyses show that a quarter of the variance in filial norms
can be explained by the family of origin. The family of origin has a smaller influence on normative obligations toward children and other family. Part of the total family influence can
be explained by the filial norms that parents have themselves and the emphasis parents
put on obedience. Family background characteristics are less important.
