This chapter uses the familial epitaphs of Roman Hieradoumia to reconstruct typical household forms in the region. The methodological problems of inferring family structure from patterns of funerary commemoration are discussed in detail. Typical ages of men and women at first marriage can – with caution – be extrapolated from changes in commemorative practices over the human life cycle; the relative prevalence of close-kin marriage is difficult to judge. Quantitative analysis of patterns of commemorative groups (presence or absence of pre-marital kin; prominence of the father’s brother among commemorators of unmarried persons) very strongly indicates that patrilocal residence after marriage was standard in Roman Hieradoumia. As a result, the typical household forms in the region seem to have been ‘patriarchal’ family households (several married sons co-residing with their father) and frérèche households (several married brothers residing together), a pattern which may also be reflected in the region’s typical inheritance practices.
