Vem daterade Charles Ferdinand, Duke of Berry?

Charles Ferdinand d'Artois, Duke of Berry (24 January 1778 – 14 February 1820), was the third child and younger son of Charles, Count of Artois (later King Charles X of France), and Maria Theresa of Savoy. In 1820 he was assassinated at the Paris Opera by Louis Pierre Louvel, a Bonapartist. In June 1832, two years after the overthrow of Charles X, an unsuccessful royalist insurrection in the Vendée was led by Charles Ferdinand's widow, Marie-Caroline, in an attempt to restore their son Henri, Comte de Chambord, to the French throne.

Amy Brown (8 April 1783 – 7 May 1876) was the English mistress of Charles Ferdinand, Duke of Berry, younger son of King Charles X of France and Marie Thérèse of Savoy. Some authors have stated that they married in a secret ceremony which was conducted in England by her father, a Protestant pastor, but there is no evidence of it. Together they had two daughters; however, when he returned to France, he was constrained to put an end to his relationship for reasons of state.
