Fulk and Hugh, then an archdeacon, witnessed a diploma of Manasses, then count, for the same monastery in 1097. In 1117, Fulk and Guy subscribed the privilege in which Manasses founded a monastery dedicated to Saint Leonard in the suburbs of Guînes. He received the lordship of Beirut after his relative, King Baldwin I of Jerusalem, conquered it, as related in the anonymous short poem, "Verse on the Illustrious Men of the Diocese of Thérouanne who went on the Holy Expedition":
Fulk was dead by 1125, when Walter of Brisebarre was Lord of Beirut.
According to Lambert of Ardres he was buried in Palestine: "Fulk, count before Beirut in the promised land there finally buried" (Fulconem in terra promissionis comitem apud Baruth, ibique demum sepultum).
