Francesco Ferdinando was the son of Alfonso d'Avalos, VI marquis of Pescara and II of Vasto. Still a child, he was named in 1536 Gran Camerlengo of the Kingdom of Naples. At the head of the Spanish army in Lombardy and Piedmont since December 1555, he achieved an advantageous truce with France in March 1556, concluding the successful campaign started by the Duke of Alba.

He also became a knight in the Order of the Golden Fleece.

In 1552 he married Isabella Gonzaga, daughter of Federico II Gonzaga. They had:
 * Alfonso Felice d'Avalos d'Aquino d'Aragona (1564–1593), prince of Francavilla and his successor.
