In page Marie Thérèse Louise of Savoy, Princesse de Lamballe:

"

In 1768, at the age of 19, having been married for just a year, Marie Thérèse became a widow when her husband died of a venereal disease at the Château de Louveciennes,[citation needed] nursed by his spouse and sister.[6] Marie Thérèse inherited her husband's considerable fortune, making her wealthy in her own right. Her father-in-law successfully persuaded her to abandon her wish to become a nun and instead stay with him as his daughter.[7] She comforted him in his grief, and joined him in his extensive charitable projects at Rambouillet, an activity which earned him the name "King of the Poor" and her the nickname "The Angel of Penthièvre".[8]
