Family background

Although a junior member of the House of Ligne, he founded a distinct cadet branch of that princely family – upon the death of his childless maternal uncle, Louis Jean Marie de La Trémoille, prince étranger, he legally appended his mother's surname (de La Trémoïlle) to his father's surname (de Ligne) in Belgium.

Marriage and children

On 11 March 1942 in Paris, France, he married Maria del Rosario de Lambertye-Gerbeviller (14 October 1922 - 17 March 2023), daughter of Charles Edmond de Lambertye, Marquis de Gerbeviller. They had three children, all of whom married into princely families: His legal title and style in Belgium was: "His Highness Jean Charles de Ligne de La Trémoïlle, Prince de Ligne."
