On this day, 9 December 1793 Yolande Martine Gabrielle de Polastron, Comtesse de Polignac died, some say as a result of a broken heart, some say from consumption. She was a confidant of the Queen Martyr and Governess to the Royal Children, including the future Louis XVII of France and Marie-Thérèse Charlotte de France, Madame Royale.
A article has appeared on Elena-Maria Vidal's blog under the title Madame de Polignac and the Politics of Calumny, on December 6, 2007.
You may find Gabrielle de Polastron in the historical novels, Trianon, see here, and Madame Royale, see here.
