Biography
On the death of his father in 1414, the ten year old Jean inherited the barony of Montmorency and several Lordships, including those of Écouen, Damville and Conflans. He was initially placed under the regency of his mother, Philippine, who died around 1419. In 1422, he married Jeanne de Fosseux (died 12 September 1431), daughter of Jean de Fosseux and Anne de Preures. Jeanne had also inherited a number of lands, principally in Flanders.
Jeanne de Fosseux's father was a favourite of Duke of Burgundy, John the Fearless. When Jeanne died in September 1431 she was buried at the Cordeliers de Senlis, and she left to her husband Jean her wealthy lands which were enclosed within the territory held by the house of Burgundy.
In 1443 Jean married for a second time, his new wife being Marguerite d'Orgemont, widow of the knight Guillaume Broullard and great-granddaughter of the French chancellor Pierre d'Orgemont, Lord of Chantilly.
Jean de Montmorency fought alongside King Louis XI against the self-proclaimed League of the Public Good, led by the Duke of Burgundy, Charles the Bold. His two sons, Jean III (later Jean de Nivelle) and Louis de Montmorency-Fosseux (from his first wife Jeanne de Fosseux), refused to join him and sided with Charles the Bold. Jean de Montmorency then decided to disinherit his two elder sons in favour of Guillaume, his third son, and the first son from his marriage to Marguerite d'Orgemont. The elder sons were officially disinherited on 24 July 1463, the pronouncement held at the Château de la Chasse, situated in the centre of the forest of Montmorency.
