General Notes

Jeanne succeeded to the County of Aumale in 1239 at the death of her father and to those of Ponthieu and Montgomerie in 1251. She married after 1237 Ferdinand III, called the Saint, King of Castile and Leon. She had been contracted in marriage to Henry III of England, who had, indeed, married her by proxy, but St. Louis (Louis IX of France) compelled her father to break this alliance, which was in contravention of one of the conditions of his pardon in 1230 that he should not give his daughters in marriage to a declared enemy of the King. Ferdinand died May 30, 1252, and Jeanne returned to France with Prince Ferdinand, her eldest son. She married 2nd Jean de Nesle and died at Abbeville March 26, 1279. By King Ferdinand she had three sons, who died before her, and a daughter, Eleanor of Castile, the wife of Edward I, King of England.
