Will by which Fernando Nunes Barreto and his wife D. Maria Henriques, declared that they wanted to be buried in the main chapel of the Monastery of Santa Clara. They founded an entail, using some "herdades" located in the parish of São Cosme, in Gondomar, and some houses in Porto. They designated their eldest son to be its first administrator, with the obligation to order the celebration of masses in this monastery and to contract chaplains. They wanted to unit this entail to another called "Morgado dos Freiriz", founded by Fernando Nunes Barreto's grandparents, Fernão Nunes and Isabel Ferraz, which was obligated to the celebration of masses in the Church of Freiriz. This entail should follow the conditions of his grandparents' entail. Fernando Nunes Barreto also declared that he was the administrator of another entail founded by his great-grandmother Beatriz Ferraz, that was obligated to the celebration of 15 masses each year in the Convent of São Francisco, using the rents of a "casal de Campo”, in Avintes. He also succeeded in the entail founded by Filipa Rebelo and Isabel Cardoso, mother and grandmother of Fernão Nunes, with the obligation to celebrate two masses in the altar of Jesus, in the Monastery of São Domingos, using the rents of some "casais" in the parish of Rebordosa, and some houses in Vale de Pegas. Finally, he was the administrator of Catarina Ferraz's entail, with the obligation to celebrate 13 masses in the Altar of São Gonçalo, in the Monastery of São Domingos, using the rents of some houses. All of these three entails of which he was the administrator should be succeeded by the eldest son. Followed by an approval deed dated 1596-05-05.
