Jean Charles, Prince de Ligne de La Trémoille

Jean Charles Lamoral of Ligne-La Trémoïlle (16 June 1911 – 9 July 2005) was a Belgian nobleman and the son of Henri-Florent Lamoral de Ligne and his wife, Charlotte de La Trémoille (1892–1971), eldest daughter of the 13th and penultimate Duc de Thouars.

Although a junior member of the House of Ligne, he founded a distinct cadet branch of that princely family: at the death of his childless maternal uncle, Louis Jean Marie de La Trémoille, prince étranger and last Duke of Thouars in France, Prince Jean Charles legally appended his uncle's surname, "de La Trémoïlle", to his own in Belgium.

On 11 March 1942, he married in Paris, France Maria del Rosario de Lambertye-Gerbeviller, 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."
