La Rochefoucauld-Montbel married Pascale Marie Subtil, a financial controller and auditor (Dauphine University), in January 1984 in
Connantre. He succeeded his father as Prince (
Fürst) de La Rochefoucauld, a title granted to his great-grandfather Jules by the
King of Bavaria in 1909. He also holds the French title of Count de La Rochefoucauld-Montbel. The La Rochefoucauld-Montbel family is listed in the
Almanach de Gotha. The princely branch of the family is closely associated with the
Marian apparitions of Pellevoisin in France and with the discovery of the
Lascaux Caves, which they once owned. This branch descends from the Dukes of Estissac and, through marriages, is connected to the
Borghese of Roman nobility. == Education and activities ==
