Inasmuch as I have written an ample discourse, collected from the Chronicles and genealogical works of Portugal and Castile, concerning the genealogy of the Alboquerques, their antiquity, and the origin and derivation of the name, which descends by the direct line of the kings of Portugal, Leon, and Castile, for the information of those who are descended from the family, I will not say here more than is necessary for the understanding briefly whence this great Afonso Dalboquerque is descended, and whose son he was.

It is in this way that the pedigree stands. The King D. Dinis, King of Portugal, had by Dona Aldonsa de Sousa, a court lady of high quality, native of Galicia, a natural son, who was called D. Afonso Sanches, and married Dona Tareja Martinz, granddaughter of the king D. Sancho of Castile, surnamed the Brave, and had with her for her dowry the town called Villa de Conde, in Portugal, and many lands in Castile, and Castle Dalboquerque, which he rebuilt, and laid the foundation of the town below it, surrounding it with a wall, tower, barbican, and moat, and peopled it with Portuguese and Castilian families; and then he took up his abode, and over the principal gateway of the town he placed a shield of his arms, which are here figured. These are the arms that the Alboquerques descended from him ought to bear, and not those which they do bear.
