Arnold II of Boulogne
Arnold II is a Count of Boulogne identified by Morton and Muntz as the one slain in battle by Count Enguerrand I of Ponthieu. Frank Barlow prefers to retain the traditional identification of the slain count as Baldwin I of Boulogne. However, he admits that the identification is "uncertain." In any case, the widow of Baldwin / Arnold then married Count Enguerrand I.
