Prince Jean Charles de Ligne de La Trémoïlle (16 June 1911 – 9 July 2005) was a Belgian nobleman and the son of Prince Henri de Ligne and his wife, Princess 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 kept alive one of the most distinguished names in French history by having his uncle's surname, "de La Trémoïlle", legally appended to his own in Belgium.
Marriage and Children
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:
- Princess Hedwige Marie (b. 1943); who married at Antoing, Belgium in 1966 Prince Charles de Merode (b. 1940).
- Prince Charles-Antoine Lamoral (b. 1946), who married firstly in 1971 Lady Moira Forbes, daughter of the 9th Earl of Granard and his wife, Marie-Madeleine de Faucigny-Lucinge; after their divorce in 1975, he wed secondly at Neuilly-sur-Seine, France on 23 January 1976 Princess Alyette de Croy (b. 1951), from whom he was divorced in 2002. He has issue by the second marriage:
- Princess Nathalie Marie (1948–1992); who married at Saint-Georges-sur-Loire, France in 1973 Prince Alain de Polignac (b. 1940).
His legal title and style in Belgium was: "His Highness Jean Charles de Ligne de La Trémoïlle, Prince de Ligne."
However, as the House of La Trémoïlle was also of princely rank in France, members of this branch are commonly referred to as Son Altesse Prince/Princess Firstname de Ligne de La Trémoïlle.
