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. Historian Martin Rheinheimer associates Elinand with Elias, who was William I's nephew. William I referred to Elias and his brother, William, as his heirs in 1126. Rheinheimer also says, the brothers were the sons of William I's brother, Godfrey. Godfrey was killed during a plundering raid in the spring of 1119.
Hans Eberhard Mayer refutes the association of Elinand with William I's nephew, emphasizing that the Biblical name,
Elias, cannot be identical with the
Germanic Elinand. Historian Malcolm Barber identifies Elinand as William I's second son. Mayer underlines that nothing proves that Elinand was William I's kinsman. Mayer also notes, Elinand's otherwise rare name is well-documented in the region of
Saint-Omer and
Fauquembergues in the 12th century. 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. He tentatively identifies Elinand's father with Hosto of Fauquembergues, who was castellan of Saint-Omer in the late 1120s, although no document evidences that Hosto fathered children. ==Prince of Galilee==
