He was the son of Alfonso IX of León and Berenguela of Castile.
Through his second marriage he was also Count of Aumale.
Ferdinand III was one of the most successful kings of Castile, securing not only the permanent union of the crowns of Castile and León, but also masterminding the most expansive campaign of Reconquista yet.
By military and diplomatic efforts, Ferdinand greatly expanded the dominions of Castile into southern Spain, annexing many of the great old cities of al-Andalus, including the old Andalusian capitals of Córdoba and Seville, and establishing the boundaries of the Castilian state for the next two centuries.
Ferdinand was canonized in 1671 by Pope Clement X and, in Spanish, he is known as "Fernando el SantoSan Fernando" or "San Fernando Rey".
Places such as the cities of San Fernando, Pampanga and San Fernando, La Union; the Diocese of Ilagan and the San Fernando de Dilao Church in Paco, Manila in the Philippines; and in California, United States, the City of San Fernando and the San Fernando Valley, were all named after him (namesakes) and placed under his patronage.

Mayor Rodriguez de Balboa was daughter of Pedro Rodríguez de Balboa, chamberlain of the Infante Henry of Castile.
The exact date of birth of Enrique Enríquez is not known.
Some authors say he was born in Andalusia around 1246.
Others think he was born in Italy during one of the periods when the Infante Henry was staying there.
There is some doubt about his paternity, since the Infante Henry did not name him or his mother in his will, despite naming many of his servants.
On 27 July 1253 his uncle, Alfonso X of Castile the Wise, gave Enrique Enríquez the lordship of La Puebla de los Infantes, in the present province of Seville.
Enrique Enríquez married Estefanía Rodríguez de Ceballos, Lady of Villalba de los Barros and of Vado de las Estacas.
She was daughter of Rodrigo González de Ceballos, Alcalde Mayor of Toledo and" Adelantado Mayor" of Murcia, and María Fernández de Caviedes, Lady of Caviedes, Lamadrid and La Revilla.
One son was born of the marriage, Enrique Enríquez the Younger.
In 1307 his wife ceded the lordship of Villalba de los Barros to Enrique Enríquez the Younger, with the consent of Enrique Enríquez.
The grant was confirmed by a document issued in the city of Valladolid on 12 April 1320 by King Alfonso XI of Castile.
The date when Enrique Enríquez died is unknown, but must have occurred before 28 February 1323.
On that date his wife described herself as a widow in a document issued in the city of Seville, when she sold a house.
Enrique Enríquez the Younger inherited his parents' possessions and served kings Alfonso XI of Castile and Peter of Castile, who awarded him several grants.
