Will made by Maria de Siqueira da Fonseca in which she ordered, among several other dispositions, the foundation of an entail with a perpetual mass obligation of a daily mass celebrated on her chapel of N. Sra. da Conceição, in the convent of S. Francisco of Crato, where her body should be buried. She left very detailed instructions for the ornamentation of the chapel and ordered the administrator to make a lamp in silver, which should always be kept lit. She named her nephew Brás Félix de Abreu as first administrator of the entail, and his eldest son Diogo Caldeira after him, and after the death of Diogo, the succession should always continue on the eldest male heir. If Diogo had no children, the administration should be handled to António de Abreu, nephew of the institutor, or her nieces Elvira or Mariquita, in this order. No administrator could ever marry with a person who descended from hebrews, moors or new-christians.
