Marie Leszczyńska
In 1725, she became "Surintendante de la Maison de la Reine" of the new Polish-born queen, Marie Leszczyńska. She was secured this post thanks to her brother Louis Henri, Duke of Bourbon who had helped secure the marriage of Marie Leszczyńska to Louis XV. At the death of her cousin Louise Diane d'Orléans in 1736 after a difficult childbirth (the child was a stillborn), Marie Anne was asked to go to the Château d'Issy to represent the Queen in honour of Louise Diane's early death.
