According to a widespread scholarly theory, Elinand was related to William I of Bures, who received the Principality of Galilee from Baldwin II of Jerusalem in 1119 or 1120.
[7] Mayer also notes, Elinand's otherwise rare name is well-documented in the region of Saint-Omer and Fauquembergues in the 12th century.
[8] He concludes that Elinand was most probably a member of the Saint-Omer family, and thus he was related to the second prince of Galilee, Hugh of Fauquembergues.
[2] Mayer argues that Elinand seized Galilee with the support of Queen Melisende of Jerusalem, who had forced William I into exile after the death of her husband, King Fulk.
[11][12] Along with Manasses of Hierges and Philip of Milly, Eliland was appointed by Melisende to lead a relieve army to the town.
[14] According to gossips which had started to spread among the crusaders during the siege, Mu'in ad-Din Unur, the ruler of Damascus, bribed Elinand.
[16][17] On the other hand, Mayer and Peter W. Edbury propose that Ermengarde of Ibelin was the wife of William I of Bures.
