Ferdinand de la Cerda
He married in November 1268 to Princess Blanche of France, the daughter of King Louis IX of France. They had two sons:
- Alfonso (1270-1324), who married Mafalda of Narbonne.
- Fernando (1275-1322), who married Juana Nunez de Lara
Ferdinand predeceased his father in 1275 at Ciudad Real. His sons did not inherit the throne of their grandfather, since their uncle, the second son, Sancho, enforced his claim, even by rebelling.
