Duke of Segorbe

Duke of Segorbe is an hereditary title in the peerage of Spain, accompanied by the dignity of Grandee and granted in 1469 by John II of [Aragon and Navarre|John II of Aragon] to Enrique de Aragón, son of Infante Henry, Duke of Villena by his second wife, Beatriz de Pimentel, from whom the Ducal line of the House of Medinaceli descends.

Current Duke of Segorbe

Don Ignacio Medina y Fernández de Córdoba succeeded in 1969 as 19th Duke of Segorbe before marrying Princess Maria da Glória of Orléans-Braganza, former wife of Alexander, [Crown Prince of Yugoslavia], in 1985.
The Duke and Duchess of Segorbe have two daughters:

Sol María de la Blanca Medina y Orléans-Braganza, 54th Countess of Ampurias, heiress apparent to her father's titles; married to Pedro Domínguez-Majón.
Ana Luna Medina y Orléans-Braganza, 17th Countess of Ricla ; married to Giovanni Rapazzini de Buzzaccarini.

Succession

As with other Spanish noble titles, the dukedom of Segorbe descended according to cognatic primogeniture, meaning that females could inherit the title if they had no brothers. That changed in 2006, since when the eldest child can automatically succeed to noble family titles.
