This paper examines the spiritual kinship known in Italian as comparatico ‘godparenthood’, as it is practised among families originating from specific rural areas of Calabria, southern Italy, who live in Adelaide, South Australia. In the Catholic rite of baptism, the compare (godparent) is a person who promises to share the responsibility of the child’s education with the parents. For the participants of the present study, however, the relationship among compari (godparents) is much more than that, perhaps being better translated as ‘family allies’. Comparatico is a strong relationship that involves not merely the people directly concerned in the religious ceremony, but all members of the two families, leading to the creation of an extended and fictive family, or alliances across multiple families. The paper shows that such inter‐familial cooperation among migrants and their descendants appears to be highly visible among Italians originating from Calabria. Yet it questions why godparenthood ties are even present in a community of Calabrian‐Italian‐Australians. I draw on folklore and network theories particularly, and the Bourdieusian concept of social capital is especially crucial in interpreting the ties of family alliances that exist in the Calabrian diasporic community of Adelaide.
