Will made by Matias Durão, in which he ordered, among other dispositions, the foundation of an entail with a perpetual mass obligation of sixty masses celebrated every year in the church of S. Francisco's convent, in Portalegre, where his body should be buried. He named his legitimized son Manuel as first administrator and his eldest male heirs after him. However, if Manuel had no children, then his three nephews António Vaz, Manuel Gonçalves and Manuel Nunes would share the administration of the entail during their lifetimes, and their sons and heirs after them, with the condition that each of them would celebrate twenty masses, perpetually, as long as the world lasted.
