Hugh II of Ponthieu was count of Ponthieu and lord of Abbeville, the son of Enguerrand I of Ponthieu.^[1] Evidently, Hugh II was the half-brother of Guy, who became the bishop of Amiens; Fulk, who became the abbot of Forest l'Abbaye; and Robert. However, it is possible that both Robert and Hugh II were the sons of Enguerrand's first wife, and Guy and Fulk the sons of a later wife that Enguerrand I married when he was in his forties.
