William of Gellone - Later References

Later References

In 1972 historian Arthur Zuckerman published A Jewish Princedom in Feudal France, a book about the dynasty of Makhir of Narbonne published by Columbia University Press. In that book Zuckerman argued that it was possible that William of Gellone was in fact one of the sons of Makhir, who he identified with the individual known in medieval sources as "Theodoric, King of the Jews of Septimania." Zuckerman made no definitive conclusions on this point, and the suggestion has since been refuted. (Graboïs, Aryeh, "Une Principaute Juive dans la France du Midi a l'Époque Carolingienne?", Annales du Midi, 85: 191-202 (1973); N.L. Taylor, "Saint William, King David, and Makhir: a Controversial Medieval Descent", The American Genealogist, 72: 205-223.)

William, listed under the name "Guillem de Gellone", is a prominent figure in the pseudohistorical book Holy Blood Holy Grail. The book claims that William was the son of Theodoric, and that since Theodoric was Merovingian, that meant that William was Merovingian as well, and plus was a "Jew of royal blood". The book goes on to state that "modern scholarship and research have proved Guillem's Judaism beyond dispute." It should be noted, however, that many other claims in the book which were listed as "fact", were later proven to be false (such as the existence of the Priory of Sion), because the authors were basing much of their researches on "medieval documents" which were later shown to be forgeries.

The importance of citing William's noble heritage and Judaism, was so that the authors could prove a genealogical link between the House of David, the Merovingian nobility, and France, in order to make a case that the Holy Grail was actually the bloodline of Jesus that had worked its way into the bloodline of Frankish royalty. This line of reasoning was later incorporated into the plot of the bestselling novel The Da Vinci Code and from there into various television documentaries.
