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
On 9 January 1778, Marie-Aurore gave birth a son, Maurice-François-Élisabeth Dupin de Francueil, in Le Marais district of Paris; his baptism took place on 18 January, being his godfather the Marquis François de Polignac and his godmother Élisabeth Varanchan, by marriage Madame de Chalut. The only child of Marie-Aurore and Louis-Claude Dupin de Francueil, he was named after his maternal grandfather, the Marshal de Saxe, and both godparents.
