Bourbon-Penthièvre
Louise Marie Adélaïde de Bourbon was first known as "Mademoiselle d'Ivoy", then "Mademoiselle de Penthièvre". In April 1769, she married her distant cousin, the duc de Chartres, who inherited the title of duc d'Orléans at the death of his father, Louis-Philippe I d'Orléans in 1785, but took the name Philippe Egalité during the French Revolution of 1789. Mlle de Penthièvre had brought with her a dowry of 6 million livres, and an annual allowance of over 500,000 livres. Upon the death of the duc de Penthièvre in 1793, the Bourbon-Penthièvre fortune Louise Adélaïde was to inherit was confiscated by the revolutionary government. It is only after her return to France during the First Bourbon Restoration of 1814 that she was able, through numerous legal battles, to regain what was left of some of her land estates, many of them having been either sold, gutted or nearly destroyed during the Revolution.At the Palace of Versailles, the family also occupied a suite of apartments located on the ground floor of the Palace underneath the "Grand Appartement du roi". Originally called the Appartements des Bains, they were the former apartments of Françoise-Athénaïs de Montespan, the mother of the duc du Maine, the comte de Toulouse, the duchesse d'Orléans and the princesse de Condé.
