Pauline de Talleyrand-Périgord

Joséphine Pauline de Talleyrand-Périgord (29 December 1820, Paris – 1890), marquise de Castellane by marriage, was a French noblewoman.

The third legitimate child of the duke and duchess of Dino, Dorothea von Biron and her husband Edmond de Talleyrand-Périgord, she is often thought to have in fact been fathered by Charles-Maurice de Talleyrand-Périgord, prince of Bénévent. She grew up in Talleyrand's hôtel particulier on rue Saint-Florentin, was nicknamed "angel of the house" and "my dear Minette" by him, and held a great affection for him throughout her life.

In 1839, Pauline de Talleyrand-Périgord married Henri de Castellane, eldest son of the marshal de Castellane. Widowed in 1847, she spent the rest of her life at the château de Rochecotte (Indre-et-Loire), which she was given by her mother. A great friend of Félix Dupanloup, bishop of Orléans, she lived a simple and devout life.
