John Oliver

(male) English form of Latin Io(h)annes, New Testament Greek Iōannēs, a contracted form of the Hebrew name Johanan ‘God is gracious’ (the name of several different characters in the Old Testament, including one of King David's ‘mighty men’). John is the spelling used in the Authorized Version of the New Testament. The name is of great importance in early Christianity: it was borne by John the Baptist (the precursor of Christ himself, who baptized sinners in the River Jordan), by one of Christ's disciples (John the Apostle, a fisherman, brother of James), and by the author of the fourth gospel (John the Evangelist, identified in Christian tradition with the apostle, but more probably a Greek-speaking Jewish Christian living over half a century later). The name was also borne by many saints and by twenty-three popes, including John XXIII (Giuseppe Roncalli, 1881–1963), whose popularity was yet another factor influencing people to choose this given name. It was also a royal name, being borne by eight Byzantine emperors and by kings of Hungary, Poland, Portugal, France, and elsewhere. Among numerous bearers of note in recent times have been American president John F. Kennedy (1917–63) and British pop singer John Lennon (1940–80). In its various forms in different languages, it has been the most perennially popular of all Christian names.

English, Scottish, Welsh, and German: from the Old French personal name Olivier, which was taken to England by the Normans from France. It was popular throughout Europe in the Middle Ages as having been borne by one of Charlemagne's paladins, the faithful friend of Roland, about whose exploits there were many popular romances. The name ostensibly means ‘olive tree’ (see Oliveira), but this is almost certainly the result of folk etymology working on an unidentified Germanic personal name, perhaps a cognate of Alvaro. The surname is also borne by Jews, apparently as an adoption of the non-Jewish surname.
