Entail foundation deed made by Duarte Gomes da Silveira in which he ordered, among several dispositions, the foundation of an entail and chapel of the invocation of Salvador do Mundo in the church of the Misericórdia of Paraíba's captaincy, with a perpetual pious obligation of four masses celebrated every week as long as the world lasted and one sung mass on the day of Nossa Senhora das Neves. He named his son in law António Barbalho Bezerra and his wife Joana Gomes da Silveira, daughter of the institutor, as first administrators of the entail during their lifetimes, and, after their deaths, the succession should always continue, preferably, on the eldest male heir. No administrator could ever marry with a another person of the so-called 'infected races', under the penalty of loosing the administration. He recomended that no administrator should ever rise his own children with wine, as a root of sin. All administrators should annex one third of their own reserved portions to the entail. The institutor also disposed that all administrators should bear the surname Silveira and the coat of arms of the Gomes and Bezerras, adding a motto beneath it with the words Verdade e Felicidade (truth and happiness) that should be present in all their seals, chairs, curtains.
