It is difficult to distinguish between the forms of the French Eberulf, and the German Eberhard, who was abbot of Einsiedlen in 934; indeed, it is highly probable that the Norman St. Evrhault, though derived from a saint Latinized as Eberulfus, and in German called Erulf, was supposed to be the same as Eberhard, and that this accounts for the English form of Everard, which sprung up from the four Evrards of the Domesday roll after the Conquest.  Eberhard hardly reaches the rank of saint in the Roman calendar; but his exertions in a great famine that ravaged Alsace, Burgundy, and Upper Germany, in 942, account for the nationality of his name in all that region.
