Victor Amadeus II of Sardinia
Louis Victor was born at the Hôtel de Soissons, the Parisian home of his ancestor Marie de Bourbon, Countess of Soissons, to Victor Amadeus I, Prince of Carignano and his wife Maria Vittoria di Savoia. His father was a grandson of Thomas Francis, Prince of Carignano and thus a descendant of Charles Emmanuel I, Duke of Savoy and Infanta Catherine Michelle of Spain. He was doubly descended from the latter pair, as his mother was a legitimated daughter of Victor Amadeus II of Sardinia and his mistress Jeanne Baptiste d'Albert de Luynes.
