de Silva Fernández de Híjar Portugal y Guterbey (1900-1934) married Don Jacob Fitz James Stuart (1878-1953) IX Duke of Berwick and XVII Duke of Alba. In this way, by matrilineal descent, the Spanish lineage of the De Silva joined the dukedom of Híjar and its titles with the House Fitz James Stuart y de Silva Fernández de Híjar Portugal. Whereas the descendants of Don Jaime have just the titles of Dukes of Lecera and Dukes of Bournonville, the Fitz James Stuart y de Silva hold, actually, the majority of the titles of the House De Silva. Heraldry De Salazar, in his “Historia Genealogica de la Casa de Silva ” writes that ”the Casa de Silva, like many in Spain, uses a heraldic device very different from the name by which it is known. Don Melchor de Teves refers (in the book de la Casa de Lerma) that on an ancient tomb of the de Silva family there is a rampant Crowned Lion. It seems that the first to use on his shield the symbol of the Lion was the Count don Gomez Paéz de Silva, who lived in the 12th century. He did it to remind his origin from the Royal House (Casa de Leon); to wear in their honour the same device as the House princes and to hand down to posterity the memory of his evident descendance from it... Drawing and painting the weapon (a rampant Lion of crimson colour, golden crowned on a silver background) exactly in the same way as the kings de Leon, Ovjedo and Galizia”. Others say that the count don Gomez Paéz de Silva was, for the same reasons, referring to the house of Borgogna, being his grandfather Gutirrez Pelaéz de Silva (1030-1110) the first to use the patronymic De Silva, vassal and counsellor of Henry of Borgogna count of Portugal. Other primary Heraldries which characterize the House de Silva Fernández de Híjar Portugal are the ones of both the Fernández de Híjar house and of the Portugal family. The first, of the Fernández de Híjar , shows the fusion of the lineages of Aragon and Navarra. In the shield of Pedro Fernández de Híjar (the bastard son who king Jaime I of Aragon had from doña Isabel Berenguela Fernández, granddaughter of the king of Navarra) we can see the five golden vertical bands alternated by four red vertical bands (de cuatro palos
