Adolphe Sax
Antoine-Joseph Sax was born on 6 November 1814, in Dinant, in what is now Belgium, to Charles-Joseph Sax and his wife. While his given name was Antoine-Joseph, he was referred to as Adolphe from childhood. His father and mother were instrument designers themselves, who made several changes to the design of the French horn. Adolphe began to make his own instruments at an early age, entering two of his flutes and a clarinet into a competition at the age of 15. He subsequently studied performance on those two instruments as well as voice at the Royal Conservatory of Brussels.
Marie-Aurore de Saxe
In her autobiography, "Histoire de ma vie", Sand describes the origins of her grandmother, Marie-Aurore de Saxe, after researching in archives and libraries. She cites in particular the judgment of the Parlement of Paris dated 15 May 1766 and the work of Jean-Baptiste Denisart, attorney at the Châtelet in Paris, "Collection de décisions nouvelles et de notions relatives à la jurisprudence actuelle", in his edition of 1771, Volume III, page 704:
