On 16 July 1435, at the age of twenty, Jeanne married Louis of Luxembourg,
Count of Saint-Pol, Brienne, de Ligny, and Conversano, Constable of France (1418 – 19 December 1475). The marriage took place at the Chateau de Bohain. She was Louis' first wife. Louis was the eldest son of Peter of Luxembourg, Count of Saint-Pol, Brienne, and Conversano, by his wife
Margaret de Baux. Louis had been brought up by his paternal uncle, who was Jeanne's stepfather,
John II of Luxembourg, Count of Ligny and Guise; therefore the young couple were well-acquainted with one another. John designated Louis as his heir to the counties of Ligny and Guise, but upon John's death in 1441, King
Charles VII of France sequestered the estates and titles. The title of Ligny was eventually restored to Louis. The title and estates of Guise were given to Louis' youngest sister, Isabelle as her dowry, which passed to her husband,
Charles, Count of Maine, upon their marriage in 1443. Jeanne succeeded as Viscountess of Meaux
suo jure upon the death of her mother in late 1450. Jeanne and Louis had seven children: •
John of Luxembourg, Count of Marle and Soissons, Governor of Burgundy (killed at the
Battle of Morat on 22 June 1476) • Jacqueline of Luxembourg (died 1511), married
Philippe de Croy, 2nd Count of Porcien, by whom she had issue. •
