Will by which João Machado de Brito, fidalgo da casa real, established an entail, designating his natural son Pedro Machado de Brito to be its first administrator. The sucessor was obligated to sell the "prazos" he possessed in order to invest in free holding assets to be incorporated into this entail. The sucessor was also obligated to order the celebration of masses in the Monastery of São Roque. This entail is composed of houses in Lisboa; the "casal de Monte Couros", on the outskirts of Mafra and Cheleiros, that he received from his father with the obligation to celebrate masses; a farm on the outskirts of Lisboa; and the "casal da Lagem", that he received from his mother. The institutor also wanted to incorporate a public debt instrument of 120 000 réis in Alfândega de Lisboa into his maternal grandparents' entail, called "Morgado de São Seris". Finally, he designated Jerónimo Henriques da Veiga to be the tutor of his son Pedro Machado de Brito. Followed by an opening deed dated 1626-01-16.
