Revocation deed through which Catarina da Silva and her husband, Gonçalo de Paiva, algibebe, revoked a bond, issued on 1644-04-02, concerning the obligation, imposed by Frei Baltasar dos Reis to them, of paying, during his lifetime, 4 000 réis, each year, to Constança da Trindade and Maria da Nazaré, Catarina and Baltasar's sisters and nuns in the convent of S. Domingos of Elvas. After Baltasar's death, Catarina and Gonçalo were obligated, instead, to support the celebration of 11 masses in a church of their choice. By annulling that document, the couple instituted the pious obligation of celebrating, each year, the referred masses for Baltasar's soul, in the church of the convent of S. Domingos of Lisboa, whose costs were to be sustained by the revenues of houses they had in Lisboa. That entail should pass to their successors.
