Afonso of Lencastre (1597—1654) was a Portuguese nobleman son of the 3rd Dukes of Aveiro Álvaro and Juliana of Lencastre. This family descended from the Infante George of Lencastre therefore they had royal blood.By a royal decree dated from 8 April 1627 King Philip III of Portugal (aka Philip IV of Spain) granted him the new title of Marquis of Porto Seguro.In spite of the Portuguese revolution of 1 December 1640 Afonso remained faithful to the Spanish Habsburgs.
