Jeffrey

English: from a Norman personal name that appears in Middle English as Geffrey and in Old French as Je(u)froi. Some authorities regard this as no more than a palatalized form of Godfrey, but early forms such as Galfridus and Gaufridus point to a first element from Germanic gala ‘to sing’ or gawi ‘region’, ‘territory’. It is possible that several originally distinct names have fallen together in the same form.
