Transnationality—defined as maintaining a sense of familyhood across national borders—is a complex process. This article studies the complexities of transnationality by analysing remittance-sending and practices of connectivity between migrants and non-migrants from the Junín region in Peru, in order to disentangle the factors that influence transnational familyhood. This analysis shows how it is the kind of family relationship between migrant and non-migrant—rather than issues such as gender, class and years of separation—that informs the transnational family relations sustained. While this might seem obvious, few studies on transnational families have analysed this factor. The combination of the various (transnational) family relationships, together with the multi-sitedness and the ideas on family obligations, characterise a transnational family.
