Gaston, Duke of Orléans
Marie Louise Gonzaga was born on 18 August 1611 in the city of Nevers, France to Charles I, Duke of Mantua, and Catherine of Guise, who died in 1618. Marie Louise was supposed to marry Gaston, Duke of Orléans in 1627, but King Louis XIII of France strongly opposed the marriage and subsequently imprisoned her in the Vincennes fortress and later in a small convent.
