Louis Jean Marie de Bourbon, Duke of Penthièvre

**Louis Jean Marie de Bourbon** (16 November 1725 – 4 March 1793) was the son of Louis Alexandre de Bourbon and his wife Marie Victoire de Noailles. He was also a grandson of Louis XIV of France and his mistress, Madame de Montespan. From birth he was known as the Duke of Penthièvre. He also possessed many titles inherited from his father and was the richest man in France during his lifetime. He was later the father in law of Philippe Égalité. Though his father was an illegitimate son of a king the young duke was still known as and given the rank of a Prince of the blood. A majority of his vast fortune had been inherited via _La Grande Mademoiselle_.  Hen was also famous for his incredible generosity to the poor of the time. He also owned the land where the future Royal Chapel of Dreux would be built.

## Marriage and children

In 1744 Penthièvre married Princess Maria Teresa Felicitas d'Este of Modena, (1726-1754), the daughter of Francesco d'Este, the Duke of Modena and Reggio, and his first cousin, Charlotte Aglaé d'Orléans. The young couple occupied a suite of apartments at Versailles which had previously been occupied by their joint ancestor Madame de Montespan. These apartments were used by the duke and his family until the reign of Louis XVI of France when the space was given to _Mesdames_, the new king's spinster aunts.

The couple had seven children, only two of whom survived infancy:
1. Louis Marie de Bourbon, Duke of Rambouillet (, 2 January 1746 – 13 November 1749) died young.
1. Louis Alexandre de Bourbon, "Prince of Lamballe" (6 September 1747 – 6 May 1768), married Princess Marie Louise of Savoy, _Mademoiselle de Carignan_ and had no children.
