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.
Maurice de Saxe
During the last years of his life, Maurice had an affair with a French lady, Marie-Geneviève Rainteau, who at that time was only eighteen years old. In 1748 she gave birth to a daughter, the last of Maurice's several illegitimate children. She was called Maria Aurora (in French: "Marie Aurore") after her grandmother. She bore the surname "de la Rivière" until 1766 when the Parlement of Paris formally recognized her parentage and she could assumed the surname of "von Sachsen" or "de Saxe". Marie Aurore married firstly in 1766 with Antoine, comte d'Horne (1722–1767), an alleged illegitimate son of Louis XV of France. By her second marriage with Louis Claude Dupin de Francueil (in 1777), she was the grandmother of Amandine Lucile Aurore Dupin, who later became famous as the writer George Sand. Maria Aurore died on 25 December 1821 when her granddaughter George Sand was seventeen. Sand included details of her grandmother's parentage in her memoires
