another son, Don Diego de Silva y Mendoza (1564-1630), I Marquess of Alenquer and III Duke of Francavilla, gave origin to the lineage De Silva Alenquer. Lineage that from the marriage between his son Don Rodrigo de Silva Mendoza y Sarmiento (1600-1664) and Doña Isabel Fernández de Ixar [(1603-1642) V Duchess of Ixar, who by her own decree created her husband Duke of Ixar, became De Silva Fernández de Ixar. The union of the two lineages, which brought to the birth of the House de Silva Fernández de Híjar Portugal, took place when don Fabrique III de Silva (1672-1700) IV Marquess of Orani, in the second half of the 17th century, married his IV degree cousin Doña Juana Petronilla de Silva Fernández de Ixar (1669-1710) VII Duchess de Ixar or Híjar. The following division of the House De Silva Fernández de Híjar Portugal into three lineages (two Spanish and one Italian), was due to three children born from the two marriages of Don Andres Avelino de Silva Fernández de Híjar Portugal y Fernández de Cordoba (1806-1885) XIV Count-Duke of Aliaga and Count of Palma del Rio. From the first wedding with Doña Josefina de Ferrari y Bonet (1819-1876) (daughter of Don Jeronimo de Ferrari of Parma, “Kapellmeister” of King Ferdinando VII of Borbone) was born Doña Josefa Maria del Carmen de Silva Fernández de Híjar Portugal (1837-1906); who, with her daughter -doña María Dolores (1861-1923)- and with Doña María Dolores's son Don Vittorio Umberto de Silva Fernández de Híjar Portugal (1881/1954) [illegitimate son whom Doña Maria Dolores de Silva Fernández de Híjar Portugal had with Don Carlos Maria Fitz James Stuart y Portocarrero Palafox (1849-1901)XVI duke of Alba] by matrilineal descent gave origin to the Italian lineage still in existence. From his second wedding with Doña Mary Caroline Elisabeth Campbell y Vincent (1820-1894) were born ten children of whom two, [Alfonso I (1848-1930) and Jaime (1852-1925)], gave origin to the two Spanish lineages still in existence, too. The Spanish lineage of Alfonso I, like it had already happened to the House De Silva Fernández de Ixar Portugal with two unions between the De Silva and the Fitz James Stuart, rejoined the descendants of James Fitz-James I Duke of Berwick (1670-1734) [illegitimate son, who James II Stuart (1633-1701) King of England had with Arabella Churchill y Drake (1648-1730) sister of John Churchill I Duke of Marlborough] when Doña Maria del Rosario
