Will made by Beatriz Caldeira de Castelo Branco in which she ordered the foundation of an entail composed of a share on the estate named Herdade de João Vaqueiro, in Monforte, over which she imposed a perpetual pious obligation of two masses celebrated every year on the mother church of Portalegre, where her body should be buried. She named her brother Gonçalo Vaz de Castelo Branco as first administrator of the entail during his lifetime and, before his death, he would appoint a person of the institutor's lineage to succeed him.
