A branch of the family became established in the Crown of Castile, after Arias Gomes de Silva was named Prince of Córdoba.

Talking about this House, it is very important, in order to understand its history, to keep in mind that, as we can see from the genealogical account above, the inheritance takes place by matrilineal descent thanks to the royal concession granted by Ferdinand the Catholic in 1483,[6] to natural children, legally recognized, of Kings.

But whatever his historical origins were, one of the most famous descendants of Don Gutierre Peláez de Silva was Don Ruy Gomez II de Silva y Meneses (1517-1573) Grande of Spain, Prince of Eboli, first Duke of Pastrana, V Lord of Ulme and Chamusca; great statesman and best friend/counsellor of Philip II of Asburgo, King of Spain.

[10] From his second wedding with Doña Mary Caroline Elisabeth Campbell y Vincent (1820-1894)[11] were born ten children of whom two, [Alfonso I (1848-1930)[12] and Jaime (1852-1925)[13]], gave origin to the two Spanish lineages still in existence, too.

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”.

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 gules) symbol of Aragon and the golden chains, symbol of Navarra, framed and cross-shaped with, in the middle, an emerald on a red background.

The second, of the Portugal-Noronhas , in the I and IV quarters, shows five blue shields cross-shaped, each with five silver bezants, placed to quincunx of the House De Portugal and, in the II and III quarters, the castle with the three golden towers surmounted by two crimson lions of the House of Castiglia and of Leon.
