The general objective of this paper is to understand the network of family relationships which involves a child who is the daughter of a teenage mother. Within this family configuration, we investigate the participation of different family members, whoever they may be: the child's father, the mother and one of the grandmothers. More specifically, we were interested in understanding the make-up of the networks of beliefs and the wishes of the people who are involved with the care and affection of this child and the ethics which govern this family group with respect to the child. We collected data using a semi-structured interview. Of the 08 families taking part in the investigation, we had access to 08 mothers, 04 fathers and 06 grandmothers, all resident in the city of Recife and having an average socio-economic and cultural standard of living. AlI the interviews were taped and literal transcripts made. We analyzed the content of the participants' narratives, seeking to detect their network of beliefs and wishes from the moment they knew they were pregnant until the date of interview. The results showed us that the natural parents normalIy get married (either legal marriage or by agreed co-habitation) soon after receiving news of the pregnancy. However, these unions do not last long. This results in the father having little contact with his child. The female presence predominates in these configurations (mothers and grandmothers). Giving care and affection is mainly the responsibility of the mothers, with maternal grandmothers helping out. Responsibility for maintaining the child also falls mainly on them. The children are regarded by family members, as being intelligent, having a good vocabulary and being the center of family attention.
