In 1639, Ettore was married to one of the richest heiresses of her time,
Giovanna "Juana" Tagliavia d'Aragona Cortés, 6th Marchioness of the Valley of Oaxaca, 5th Duchess of Terranova (1619–1692), the daughter of Diego Tagliavia d'Aragona, 4th
Duke of Terranova, and
Doña Estefanía de Mendoza Cortés, 5th
Marchioness del Valle de Oaxaca. Juana was the heiress of vast
conquistador estates in
Mexico. After their marriage and per the requirements of the
entailment, the family used the surname, "Aragona Pignatelli Cortés" for all their descendants, who were, however, generally known as "Pignatelli d'Aragona". Together, they were the parents of the following children who survived to adulthood: • Mariana Pignatelli d'Aragon (b. 1643), who married Jaime Francisco Sarmiento de
Silva, 5th
Duke of Híjar, 8th Count of Belchite, a direct descendant of
Juan Francisco Fernández de Hijar. • Geronima Pignatelli d'Aragon (1644–1711), who married Francesco Marino
Caracciolo, 4th Prince of
Avellino. • Giovanna Caterina Pignatelli d'Aragon (b. 1645), who married Francesco IV Rodrigo
Ventimiglia, 5th Prince of
Castelbuono. • Estefanía Pignatelli d'Aragon (b. 1667), who married Fernando de
Zúñiga y Enríquez de Acevedo, 5th
Duke of Peñaranda, 9th Count of Miranda. Pignatelli died on 8 March 1674 at
Madrid, in the
Kingdom of Spain. Together, Ettore and Juana established a dynasty that assembled the immense wealth of the Aragonas, the Tagliavias, the Pignatellis and the Cortés, their titles and their fiefs. ==Notes==
