Will chart made by António Pacheco da Silveira and his wife Ana de Resende in which they ordered, among other dispositions, the foundation of an entail composed of lands in the island of Santa Maria, with a perpetual obligation of one mass celebrated every week in the church of the Misericórdia of Vila Franca do Campo, where their bodies should be buried. They named their daughter Maria da Silveira as first administrator and after her death the succession should continue, preferably, on the eldest male heir. However, if she died without an heir, she would appoint a successor, and split the reserved portion of the institutors in three parts, keeping one for the entail and donating the other two to the entails founded by Ana Martins, grand-grandmother of António Pacheco da Silveira, and Francisco Nunes Velho, uncle of Ana de Resende.
