Grandee of Spain in the context of "Peerage of France"

Louis de Rouvroy, duc de Saint-Simon, GE (French pronunciation: [lwi də ʁuvʁwa]; 16 January 1675 – 2 March 1755), was a French courtier and memoirist, who also spent time as a soldier and diplomat. He was born in Paris at the Hôtel Selvois, 6 rue Taranne (demolished in 1876 to make way for the Boulevard Saint-Germain). The family's ducal peerage (duché-pairie), granted in 1635 to his father Claude de Rouvroy (1608–1693), served as both perspective and theme in Saint-Simon's life and writings. He was the second and last Duke of Saint-Simon.

His enormous memoirs are a classic of French literature, giving the fullest and most lively account of the court at Versailles of Louis XIV and the Régence at the start of Louis XV's reign. His relationship with Louis XIV was distant and difficult, but he was a life-long friend of Louis' nephew Philippe II, Duke of Orléans, who was made Regent for the infant Louis XV after the old king died. Orleans appointed Saint-Simon to his council and in 1721 made him ambassador to Spain.

Francisco Fernández de la Cueva y Fernández de la Cueva, (Genoa, Italy, 17 November 1666 – Madrid, Spain, 28 June 1724) was the 10th Duke of Alburquerque, a Grandee of Spain, a Knight of the Order of the Golden Fleece from 1707, and Viceroy of New Spain from 27 November 1702 to 13 November 1710. He was viceroy during the War of Spanish Succession and his tenure as Viceroy of New Spain is commemorated in the namesake of Albuquerque, New Mexico.

He was the nephew of Francisco IV Fernández de la Cueva – Colonna, (* Barcelona, 1618/1619 – † Madrid (Palacio Real) 27 March 1676), 8th Duque de Alburquerque and many other lesser titles, also a Viceroy of New Spain, (1653–1660), and Viceroy of Sicily, (1667–1670), and the son of the 9th Duke of Alburquerque, and many other lesser titles, the cadet brother of the 8th Duke, and inheritor of the titles, Melchor Fernández de la Cueva (es; fr; it) (* Madrid, 2 March 1625 – † Madrid 12 October 1686).

Pedro Téllez-Girón, 3rd Duke of Osuna (17 December 1574 – 24 September 1624) was a Spanish nobleman and politician. He was the 2nd Marquis of Peñafiel, 7th Count of Ureña, Spanish Viceroy of Sicily (1611–1616), Viceroy of Naples (1616–1620), a Knight of the Order of the Golden Fleece since 1608, Grandee of Spain, member of the Spanish Supreme Council of War, and the subject of several poems by his friend, counselor and assistant, Francisco de Quevedo.

He served as a footsoldier and climbed the ranks, an unusual career for an aristocrat, during the Eighty Years' War. As Viceroy of Sicily and Naples, Osuna reorganized the local administration and armadas with new strategies and ships, and implemented a highly profitable and successful privateering system against the Ottoman Empire, the Republic of Venice and the Barbary pirates. Despite opposition in the court, he maintained Mediterranean dominance during the ten years of his mandates, achieving victories like Cape Corvo, Cape Celidonia and Ragusa. At his peak, his individual naval power is believed to have rivaled that of the Sultan of the Ottoman Empire.

Francis Borgia, SJ (Valencian: Francesc de Borja; Spanish: Francisco de Borja; 28 October 1510 – 30 September 1572) was a Spanish Jesuit priest. The great-grandson of both Pope Alexander VI and King Ferdinand II of Aragon, he was Duke of Gandía and a grandee of Spain. After the death of his wife, Borgia renounced his titles and became a priest in the Society of Jesus, later serving as its third superior general. He was canonized on 20 June 1670 by Pope Clement X.
