Will by which Pedro Silveiros expresses his wish to be buried in the church of the convent of S. Francisco of Portalegre, in which he ordered the foundation of an entail composed of his remaining properties with a perpetual obligation of seven annual masses. The institutor named his niece Catarina as first administrator and, after he death, the succession should continue, preferably, on the eldest male heir. Catarina would only receive the administration when she comes of age, and until then, her eldest brother would administrate the entail as her tutor. The first administrator was obliged to make an inventory of all entailed properties.
