He married Princess Charlotte de La Trémoïlle (eldest daughter of Prince Louis Charles Marie de La Trémoille, 11th Duke of Thouars and his wife Hélène Marie Léonie Pillet-Will) and they had one son, Prince Jean Charles Lamoral. In 1933, upon the accidental death of his wife’s childless younger brother, Prince Louis Jean Marie de La Trémoille, 12th Duke of Thouars, Prince Henri-Florent Lamoral became The Duke of Thouars as spouse of the now 13th Duchess, a title which was last held in the female form by his mother-in-law Princess Hélène, The Dowager Duchess of Thouars.
