y Pimentel. Married 19 March 1802, at 17, 17th year old Françoise Philippine Thomas de Beaufort-Spontin y Toledo, (Paris 7 March 1785 – 28 January 1830), daughter of Count and Marquis Friedrich August Alex von Beaufort-Spontin, who also became c. 1782 Duke von Beaufort-Spontin (Namur 14 September 1751 – Brussels 22 April 1817), and Leopoldina de Toledo y Salm-Salm, (Madrid, 1760 – Brussels, 4 July 1792). Mariano Téllez-Girón, 12th Duke of Osuna : He represented Spain in the crowning of Queen Victoria in England and in the marriage in 1853 of Spanish aristocrat Eugenia de Montijo to Napoleon III. He is reported by Spanish diplomat and notorious writer Juan Valera, later Spanish Ambassador in the US, to have spent with him, Embassy Officer, and his extravagant Russian friends, while Spanish Ambassador in Russia (1856–1862), incredible amounts of money in Saint Petersburg. When Mariano died in 1882, aged 68, there were lawsuits from pretenders supposed to be closely connected to the family, as well as creditors racing many of the buildings, castles, lands, artworks, etc. Closer inspections around many of the accumulated nobility titles reveal that they are held now by rather ambiguous persons (legally speaking about their supposed inheritance rights). He married in Wiesbaden, 4 April 1866, Marie Eleonore zu Salm-Salm, née Princess zu Salm-Salm, (Hessen, Frankfurt am Main, 31 January 1842 – Dülmen, 18 June 1891), who became thus the 12th Duchess Consort of Osuna. She remarried to the Duc of Croy when Mariano died but there was no issue from either marriage. Notice that the Salm-Salm family had entered already within the Osuna family through the Count, Marquis and Duke Friedrich, (deceased 1817), and his first wife Leopoldina de Toledo y Salm-Salm, (deceased 1792), parents-in-law of the 10th Duke of Osuna.
