As the possessor of one of the largest fortunes in Europe, Louis Jean Marie was a very attractive marriage candidate, especially considering his close links with the French royal family.

This idea, however, was abandoned as Louise Henriette's mother wished her daughter to marry Louis Philippe d'Orléans, the heir of the House of Orléans.

In 1791, he moved to the Château de Bizy,[1] at Vernon in Normandy,[2] where his daughter joined him in April of that year after leaving her husband, the Duke of Orléans (Philippe Égalité during the French Revolution).

Nine months later, on the afternoon of 21 November 1793 a group of Jacobin radicals and their workmen broke into the chapel, with the excuse of searching for lead and destroying feudal symbols, which had recently been outlawed.

They smashed the armorial decorations, uprooted the coffins, and treated the remains of the royally-connected Penthievre family to a common pauper's burial, in a quicklime-coated pit in the nearby canons' cemetery.

Similar treatment had recently been given to the remains of the duc's executed cousin King Louis XVI in Paris, and to their ancestors at the royal necropolis of St.Denis.

In 1798 the remains of the chapel were put up for auction, and demolished as recyclable building materials by the successful bidder, a timber merchant from Chartres.

His two sons inherited his fortune and when they both died childless, the duc de Penthièvre was the sole heir to du Maine's wealth.

As a result, what she managed (after the Bourbon Restoration) to recuperate of her fortune confiscated during the French Revolution, passed, upon her death in 1821, into the possession of the House of Orléans.

In November 1783, after having sold to Louis XVI the château de Rambouillet and the immense rich-game forest attached to the estate - the latter being the main reason of the sale - Penthièvre transferred the nine bodies of his family (his parents, his wife and six of his seven children) from the 12th century Saint-Lubin church in the village of Rambouillet to the Collégiale Saint-Étienne de Dreux, where he himself was buried in March 1793.

In November 1793, a revolutionary mob desecrated the family crypt and threw the ten bodies in a mass grave in the Collégiale cemetery (cimetière des Chanoines).

In 1816, his daughter, Louise Marie Adélaïde de Bourbon, duchesse douairière d'Orléans, had a new chapel built on the site of that grave, as the final resting place for the members of the House of Bourbon-Toulouse-Penthièvre.
