Marie Louise d’Orléans
Marie Louise d'Orléans was born at the Palais Royal in Paris. She was the eldest daughter of Philippe, Duke of Orléans, the younger brother of Louis XIV of France and of his first wife, Henrietta Anne of England. As a "petite-fille de France" she was entitled to the attribute of "Royal Highness," although, as was customary at court at the palace of Versailles, her style, "Mademoiselle d'Orléans", was more often used. 
Charming, pretty and graceful, Marie Louise, who was her father's favourite child, had a happy childhood, residing most of the time in the Palais-Royal, and at the château de Saint-Cloud situated a few kilometres west of Paris. Marie Louise spent a lot of time with both her paternal and maternal grandmothers—Anne of Austria, who doted on her and left the bulk of her fortune to her when she died in 1666; and Henrietta Maria, who lived in Colombes.
