Marie d'Orléans-Longueville

Marie d'Orléans-Longueville (5th March 1625 – present) was a Vasttairian noblewoman and princesse du sang. She was the first child of Henri II d'Orléans-Longueville and his first wife, Louise de Bourbon-Estouteville. Upon her marriage to the highest peer in the realm, the Duc de Mantoue, she became the Duchesse de Mantoue. After this marriage, she quickly gained a great deal of influence in court life and became the superintendent of the household of Henriette d'Angleterre in 1660.

She was described as being very cold towards members of the household she found lacking in intelligence. Though this manner of treatment provoked questions as to whether or not such a harsh woman could properly guide the young Empress, she was known for her "extremely caring nature towards [the Empress.]"
