"Dorothea von Biron, Princess of Courland, Duchess of Dino, Duchess of Talleyrand and Duchess of Sagan, known as Dorothée de Courlande or Dorothée de Dino (21 August 1793 – 19 September 1862), was a Baltic German noblewoman. Her mother was Dorothea von Medem, Duchess of Courland, and although her mother's husband, Duke Peter von Biron, acknowledged her as his own, her true father may have been the Polish statesman Count Aleksander Batowski. For a long time, she accompanied the French statesman Charles Maurice de Talleyrand-Périgord; she was the separated wife of his nephew, Edmond de Talleyrand-Périgord." - (en.wikipedia.org 27.02.2021)
