Doña Juana married Don Jofre de Lançol; Doña Caterina married Don Juan de Mila, Baron of Mazalanes; a third daughter, whose name is missing, also married; and the offspring of these three became later of extreme importance. The son, Alonso, was born on St. Sylvester’s Eve, 1378, the year of the opening of the Great Schism, at Xativa, and baptized in the church of St. Mary in that city. He himself has told us this, in two Bulls dated 1457.[9] His youth was spent at the University of Lerida, where he specialised in jurisprudence for the degree of Doctor in Civil and Canon Law, and obtained a professorship and Holy Order. While he was a young priest (1398–1408) he chanced to assist at a sermon preached by the great Dominican Vincent Ferrer in a mission at Valencia. At the close of his discourse, the friar singled out from the crowd Don Alonso de Borja, to whom he addressed this remarkable prediction: “My son, you one day will be called to be the ornament of your house and of your country. You will be invested with the highest dignity that can fall to the lot of man. After my death, I shall be the object of your special honour. Endeavour to persevere in a life of virtue.” Don Alonso was impressed by this saying, for he repeated it to St. John Capistran in 1449, and he tenaciously waited for the fulfilment. After His election to the papacy, He performed the solemn canonisation of St. Vincent Ferrer on the twenty-ninth of June, 1455. Don Alonso proceeded from his University professorship to a canonry in the cathedral of Lerida, which was conferred upon him by his countryman Don Pedro de Luna, the Pseudopontiff Benedict XIII. Later, he entered the arena of politics as secretary to King Don Alonso I (The Magnanimous) of Naples and the Two Sicilies; and, here, his diplomatic skill and legal training raised him to the unofficial but important post of confidential counsellor to the Majesty of the Regno. Now that he was domiciled in Italy his fortunes moved swiftly. In 1429 he won the gratitude of the Lord Martin P.P. III (or V) by winning for His Holiness the support of Spain, and by negotiating the renunciation of the Spanish Pseudopontiff, Don Gil Muñoz, who called himself Clement VIII.
