Jean de Pressy, from Artois, knight: We find mention of a Jean de Pressy, King's treasurer of war in 141o among those who assisted the Duke of Burgundy in 1419 in his counsel at Arras "on the matter of the treaty with England."

In 1425 he is called counselor of the grand Council of the King, and rendered his expenses for the trip he had made to Champagne to raise aid and to pay the men-at-arms employed at the siege of Moynier.
On this mission he must have met Pierre Cauchon who was also employed in it.

Jean de Pressy is mentioned among the lords of the entourage of little Henry VI during the sojourn he made at the castle of Rouen from July 29, 1430, to November 20, 1431, and he figures among the members of the Grand Council. He accompanied the young prince to Paris. A Jacques de Pressy was at that time canon of the cathedral of Beauvais.
