thereupon recreated the title of Valentinois by letters patent, signed in December 1715 and registered on 2 September 1716, for Jacques, who was to succeed his father-in-law Antoine as Prince Jacques I; like the previous creation, its inheritance was restricted to male heirs. After Jacques's abdication in 1733, the title passed uninterrupted for several generations from Prince to Prince: from Jacques to Honoré III, Honoré IV, Honoré V, Florestan I, Charles III, Albert I. Albert bestowed the title of Duchess of Valentinois upon his adopted granddaughter Charlotte, thenceforth known as Princess Charlotte, Duchess of Valentinois, on 20 May 1919. On 20 March 1920, shortly after Charlotte's marriage to Pierre de Polignac, he, like Jacques-François de Goyon-Matignon, took the title of Duke of Valentinois, having already changed his surname to Grimaldi. Although Albert I had granted the title of Valentinois to his granddaughter Charlotte, its right to succession remained with Louis II and his legitimate male descendants; consequently, on his death without a male heir in 1949, it became extinct in French law and under Salic Law. However, his successor, Rainier III (son of Charlotte), still claimed it, possibly in the belief, as suggested by François Velde, that it was "implicitly recreated for Charlotte by the French Republic in 1919 when her adoption was approved". However, the various French Republics have never created nor re-created any dukedom. According to the Almanach de Gotha, the title used in Monaco corresponds to a Monegasque concession of a title which otherwise would not be recognized in France, specially having in account that when Charlotte was created Duchess by her father, her grandfather was still the living Prince of Monaco with the right to the title of Duke, and only his son could succeed to the French title. Beside, only legitimate children can inherit French titles.
