 There are two death notices for Erart in the necrology of the Confrérie des jongleurs et bourgeois d'Arras.One records a Jehans Erardi dying in 1258 while another records Jehan Erart dying in 1259.It is possible, when considering that his works are preserved in two different sections of the "Chansonnier du Roi", that there were two Jehan Erarts, but this is not likely.
