Baldwin III of Jerusalem
Taking into account these documents, Mayer concludes that there was only one Prince William of Galilee and "William II" was actually identical with William I. He proposes that Melisende forced William to leave the Kingdom of Jerusalem shortly after Fulk died in November 1143. According to Mayer, Melisende, who ruled the kingdom for years after her husband's death, gave Galilee to Elinand (whom Mayer supposes to have been related to a former prince, Hugh of Fauquembergues). William, Mayer continues, regained Galilee in 1153, shortly after Fulk and Melisende's son, Baldwin III of Jerusalem, started to rule independently of his mother. William was last mentioned in a charter issued on 4 October 1157.
