Louis Alphonse, Duke of Anjou
Their father has conferred upon them the historic French titles of, respectively, Duke of Burgundy ("duc de Bourgogne"), and Duke of Berry ("duc de Berry"). (In Spain, the twins are "Don" Luis and "Don" Alfonso de Borbón Vargas). Prince Louis, as Legitimist Dauphin of France, is expected to succeed his father as head of the French royal house, the senior Bourbon/Capetian line, in Legitimist reckoning. However, under Spanish law, and assuming Felipe VI does not in future father a son, the Spanish crown will be inherited by his elder daughter Leonor, Princess of Asturias, who will become queen regnant, and if Felipe does have a son, that son will inherit the Spanish throne regardless of the genealogical seniority of the Anjou branch. Louis and Alphonse were baptised on 5 September 2010 at St Peter's Basilica in Vatican City. Louis' godparents were Arancha Martínez-Bordíu and Francisco D'Agostino and Alphonse's were Amparo Corell de Trenor, and Lorenzo Perales.
Bernard-François, marquis de Chauvelin
The scion of an illustrious family, Chauvelin followed his father François-Claude de Chauvelin as "Master of the King's Wardrobe" (to Louis XVI) and fought in the Comte de Rochambeau's French Expeditionary Force. However, despite being of aristocratic birth, he had been raised with liberal views and thus became supportive of the French Revolution.
In February 1792 he married Herminie-Felicienne-Joséphine Tavernier de Boulogne de Magnanville and was posted to the Court of St. James's, styled "Ambassador's Cloak" (or Deputy Ambassador), under Talleyrand. His role in London was to persuade the British Government to remain neutral in the impending war between France and Austria and Prussia. Arriving in May 1792, Chauvelin was well received at first and secured British neutrality. However, on 10 August 1792, in light of the storming of the Tuileries and the formal suspension of King Louis XVI of France from power, Chauvelin's status became ambiguous - as his credentials had been issued by a non-ruling king and, moreover, Britain had recalled its own ambassador (and not replaced him), thereby ending official communication. Following the formation of French Republic in September, the new French republican government did not promptly renew his credentials, ending what remained of his official status at the Court of St James. Despite Chauvelin's claims to continue as interim representative of France until the arrival of his new credentials (he believed them imminent), foreign secretary William Grenville refused to recognize him as officially speaking for the French republic and returned his papers and missives. Chauvelin finally received his new credentials from the French republic in January, 1793 and requested an audience with the British king to present them. But the timing was inauspicious - Louis XVI had been sentenced to death by the French convention the day before, and would be executed a few days later (21 January). Chauvelin was ordered to leave England by 1 February 1793, as the British made preparations for war.
