Jacques Boucher, Jeanne's host at Orléans, was treasurer and later receiver of the finances of Charles, duc d'Orléans, and was a very devoted servant of that prince. His house was situated at the Renard Gate.

On February 10, 1416, Jacques Boucher is cited as clerk of the bailiffs of the Duke; he was given 14 livres to join the men at the council of Orléans at Calais, where the Duke was, in November, 1415. February and September, 1422, he replaced Pierre Renier as treasurer.

On December 18, 1422, he obtained a safe-conduct in order to treat for the ransom of the Count of Angoulême. In June, 1439, at Calais Jacques Boucher delivered to Duke Charles 40 ecus d'or "for his pleasure." On January 3, 1444, he was dead and was replaced by Jean Chardon, the Duke's secretary. Jacques Boucher was able, without doubt, to see Charles d'Orléans during his captivity.
