Eugenio of Savoy (Eugenio Ilarione; 21 October 1753 – 30 June 1785) was a prince of the House of Savoy and founder of the Villafranca branch of the royal family of Italy that survived until 1888. He was a brother of Queen Marie Antoinette's tragic confidante, the Princesse de Lamballe.
While stationed in Saint-Malo, on 29 December 1779 the 26 year-old prince secretly married 14 year-old Elisabeth Anne Magon de Boisgarin, the daughter of François Nicolas Magon, Seigneur de Boigarin, and his wife Louise de Caruel. After the wedding, held probably in the Boisgarin parish of Spézet in the Finistère, the bride assumed the title, Countess de Pommeryt. The marriage evoked a scandal, a lawsuit (conducted over many years by the renowned attorney, Lacretelle the Elder) and, eventually, an annulment ("for not having observed all the formalities prescribed by the civil and military laws of the kingdom") registered by the Parlement of Paris at the behest of Eugène's parents,[2] as well as the Kings of Sardinia and France, who objected to his elopement with the daughter of a family only ennobled since 1695, whose wealth derived from a prosperous apothecary ancestor.[3]
As the bridegroom persisted in his determination to wed Mlle de Boisgarin,[2]Louis XVI relented,[3] and King Victor Amadeus III issued a royal decree in September 1780 requiring consent of the head of the house for the marriage of princes of the blood, and morganatising marriages for brides of "inferior condition or status", whether wed with or without the royal assent. On 22 February 1781 the marriage was again solemnized at Saint-Méloir-des-Ondes, Brittany in accordance with the new Savoyard house law. Thus, the marriage, being approved in advance, was legal in Sardinia and Eugène did not thereby forfeit his own dynastic rights or princely title, but his wife and future descendants of the marriage were not recognized as members of the House of Savoy nor as in the line of succession to the throne, although allowed to bear the Savoy surname and to retain the Villafranca countship. The Sardinian king granted the couple an annual allowance of 24,000 livres, supplemented by 44,000 from the French king which, combined with Villefranche's resources yielded an annual income of 100,000 lives.[3]
The only child born of this union, a son known as the Chevalier de Savoie, inherited Eugène's property when he died in his castle at Domart, Picardy, aged 31.[3] In addition to King Louis designating his finance minister, Breteuil, to be his tutor, the young chevalier was allowed a 15,000 livres allowance, while his widowed mother was given a 6,000 livre pension.[3] Despite the Parisian mob's murder of his aunt, the Princesse de Lamballe, after the French Revolution he was made a page at the court of Napoleon I in 1812, became a colonel of the Hussars 2nd Regiment, and was promoted to lieutenant general during the Restoration.[3] The chevalier's son, Eugenio (1816-1888), lived to be designated "heir presumptive to the throne of Italy in the event of extinction of the reigning branch" in 1834.[3] Prince Eugène's Villafranca descent, although dynasticised in 1834, survives as the once-again morganatic Villafranca line,[3] headed by Edoardo, Count of Villafranca-Soissons.
