Entail foundation deed by which Constança Vicente, widow of Fernando Pires, former porteiro of the archbishop of Braga D. João de Soalhães, together with Lourenço Vaz Pires, their brother-in-law, executor and administrator of their chapel, establish an entail. They establish it according to an agreement between Constança Vicente and Fernando Pires, by which they had agreed that the last of them to die would entail both their properties and establish a chapel. This chapel should always be administered by two persons: one descendant of Fernando Pires's lineage, and another one of Constança Vicente's lineage. Constança Vicente establishes that after her death, her right of administration shall be bequeathed to Pedro Eanes de Oliveira. Lourenço Vaz Pires establishes that his right shall be bequeathed to João Lourenço, Fernando Pires's nephew, son of his "prima co-irmã". From then on, it shall pass to their descendants, in order that there's always two, one of each line. These successors shall keep the properties entailed in good condition, order a daily mass and twelve aniversários in the convent of S. Francisco of Lisboa, for the souls of the institutors. They shall also keep two chaplains, one in the church of Sta. Maria Madalena of Lisboa, and another one in the church of Santa Maria of Viana do Alentejo, the second of which must pray an annual mass in the day of St. John the Evangelist.
