This article analyzes the Nossa Senhora do Rosário de Mambucaba in Angra dos Reis City parish registers of baptisms and marriages, in the 19th century, which were supported by post-mortem inventories made byslave owners. We have checked the predominant kinds of marriages, if endogamy by origin, Africans to Africans, Creoles to Creoles, or mixed marriages. At the same time it is possible to observe how the end of the external slave trade in 1850 and the economical and demographic transformations during the second half of the 19th century influenced on the slaves' attendance in the Church to formalize their unions, and who were the single mothers.
