Juan Manuel, Prince of Villena
João Manuel (Lisbon, c. 1416 – December 1476) was a religious Carmelite, Bishop of Ceuta (1443-1459) and Bishop of Guarda (1459-1476). Although some genealogists claimed that he was the son of Edward, King of Portugal and Joana Manuel de Vilhena, great-granddaughter of Juan Manuel, Prince of Villena, Anselmo Braamcamp Freire dismisses such filiation and provides sufficient arguments against it.
