James of Artois
James of Artois (1325–after 1347) was the third son of Robert III of Artois and Joan of Valois, sister of King Philip VI. After his father was convicted of forgery and driven into English exile, the king had his nephews taken into custody.
James was confined at Nemours in 1342 and then moved with his mother and brother Robert to Château Gaillard. He died in prison after 1347, probably a victim of the Black Death, without posterity.
