This introductory chapter sets out the book's purpose, which is to present an ethnographic study of the nature of personhood, name and marriage systems, gender, kinship, and concomitant issues of ownership — all of which provide a vantage point to rethink the anthropological presumption of social relations. The book looks into the modes and behaviour of ownership as it is instantiated through items of cultural heritage, ritual action, and a system of personal names in Kanganamun, an Iatmul-speaking village on the Sepik River in Papua New Guinea.
