'Overall, the book makes a significant contribution to the literature on family structure and composition and makes an important call for the study of larger family networks. ... Widmer clearly illustrates the importance of relying on respondents' subjective reports of family rather than on preconceived notions about who relevant family members are. Families continue to matter, and the book makes it clear that people "do" family outside of nuclear families and that a network perspective is a fruitful way of understanding family dynamics.' American Journal of Sociology 'Widmer has written an interesting book which theologians and social theorists concerned with families must read.'
