Donation deed by which Sebastião Pereira and his wife Ana da Costa decided to give all their assets to Sebastião. The couple did not have any children of their own, but in view of the great affection they both had for Sebastião, who was Sebastião Pereira's natural son, they decided that he should be the heir to their estate. The property, namely the farmstead of Bastuço, was incorporated into a chapel with the task of celebrating a perpetual weekly mass in the church of Santa Maria de Barcelos, where the couple were to be buried. On the death of the couple, Sebastião would take possession of the estate, to be succeeded by his first-born son, excluding any illegitimate children from the administration. If he had no descendants, the entail was to be given to Ambrósio Pereira, who was also a legitimate son of Sebastião Pereira, or alternatively to his nephew Gaspar de Maris.
