Note 4 — THE ECCLESIASTICAL ORDERS OF KNIGHTHOOD Part II
Reading edition
F. Giraud, Le Bienheureux Gérard (Aix, 1919); Carlo Guarmani, Gli Italiani in Terra Santa, reminiscenze e ricerche storiche (Bologna, 1872), pp. 28-29. E. J. King, The Knights Hospitallers in the Holy Land (London: Methuen, 1939, p. 20), says that the theory that Gerard’s surname was Tonce or that he hailed from Tonco is based on “the error of some copyist of a Latin text, who seeing the words ‘Gerardus tunc’ mistook the adverb for a surname.”
