Will of Cristóvão Mendes de Vasconcelos, canon in the Cathedral of Braga. The testator requests that his body be buried in the Cathedral, in the place reserved for canons. He decided to establish an entail, including in this "morgado" the farmstead of Briteiros, which he had previously bought from Jorge do Vale Vieira, and other 5,000 cruzados, which were to be used to acquire other lands. The first owner of the entail would be his nephew Cristóvão Vieira, or alternatively Baltasar Vieira. Succession would be by blood, with preference given to first-born sons, excluding illegitimate children. Administrators were obliged to use the family name of Vieira. They were also obliged to establish a chapel in the church of São Salvador de Briteiros or in the convent of São Francisco de Guimarães, if the testator had not done so during his lifetime. In this chapel, the mortal remains of his parents, grandparents and future administrators of the entail should be interred.

Followed by the approval deed (1622-09-03, fls. 107-108).
