Andrés Avelino de Silva y Fernández de Córdoba, 13th Duke of Aliaga (28 November 1806 - 8 January 1885) was a Spanish aristocrat.
Andrés Avelino de Silva y Fernández de Córdoba was born on 28 November 1806 into the noble House of Silva. He was the second son of José Rafael de Silva Fernández de Híjar, 12th Duke of Híjar (1776–1863), and Juana Nepomucena Fernández de Córdoba Villarroel Spínola y la Cerda, 8th Countess of Salvatierra (1785–1813).[1] His elder brother was Cayetano de Silva y Fernández de Córdoba.
Upon the death of his father in 1863, his elder brother succeeded to the senior title of Duke of Híjar, and he succeeded to some of his subsidiary titles, including as the 13th Duke of Aliaga, 16th Marquess of Almenara, 9th Marquess of Sobroso, 10th Count of Salvatierra (from his mother), and 15th Count of Palma del Río. Upon his elder brother's death two years later in 1865, the dukedom of Híjar passed to his nephew, Agustín de Silva y Bernuy, 14th Duke of Híjar. When Agustín died in 1872, the dukedom should have reverted to Andrés Avelino, as his nephew died without issue, but the Duke of Aliaga renounced his right to the title in favor of his first-born son Alfonso, who succeeded as the 15th Duke of Híjar.
He was also a Gentleman of the Real Maestranza de Caballería de Sevilla.
On 22 February 1843 in Madrid, he married Mary Caroline Campbell, a daughter of William Johnston Campbell and the former Anna Maria Vincent (a daughter of Sir Francis Vincent, 8th Baronet). Mary was a granddaughter of Lt.-Gen. Colin Campbell and niece of Sir Guy Campbell, 1st Baronet.[2] [3] Together, they were the parents of:[4]
