Will made by André de Sousa Tavares in which he ordered, among other dispositions, the foundation of an entail with the perpetual obligation of four masses celebrated every week on his chapel in the church of S. Francisco's monastery, in Portalegre. He named his eldest son as first administrator of the entail and after his death the succession should always continue, preferably, on the eldest male heir. If this son had no male heirs, the administration should be handled to the second born son with the same condition, in ways that the male uncle should be preferred on the administration over the female niece. If none of his male or female daughters had children, then the entail should be transmitted to his brother Francisco de Sousa Tavares. All administrators were henceforth obliged to annex half of their own reserved portions to the entail by the time of their deaths. They should also bear the surname "Sousa Tavares" and use the coat of arms of Sousa and Tavares family, or, otherwise lose the administration. He ordered that all administrators should give five alqueires of oil in order to maintain a lamp permanently lit on the chapel of Espírito Santo, in Portalegre. Finally, he also left detailed instructions for the construction of a manor house on the estate of Abrunheira.
