Entail foundation deed by which Joana da Cunha, widow of António de Castro, fidalgo da Casa do Rei, revokes a previous will she had made with her husband, in which they had annexed their third parts to the entail of the estate of Carvalhal, which António de Castro had inherited from his grandmother. She declares she has annexed only the third part of her husband to that entail, and has given it to their eldest son, Cristóvão de Castro, as had been accorded. She establishes a new entail with her third part, consisting of the estates of Vidigal and Cuncos, in Montemor-o-Novo, and gives it to her other son, Nicolau de Castro, fidalgo da Casa do Rei, to always be in his lineage. She also annexes to it the legitimes of her two surviving daughters, Isabel and Jerónima do Presépio, nuns in the monastery of S. Salvador of Lisboa. The administrators of the entail shall have the obligation of ordering a daily mass and an annual one either in the church of Santa Maria of Montemor-o-Novo or in the monastery of S. Salvador of Lisboa. She donates the entail to her son, reserving for herself the usufruct of its properties during her lifetime.
