The name George was introduced in England by the Crusaders (a vision of St. George played a key role in the First Crusade), but not common until after the Hanoverian succession (18th century); so, also "Georgian" (1855) in reference to the reigns of the first four king Georges (1714-1830).

St. George began to be recognized as a patron of England in the time of Edward III, perhaps because of his association with the Order of the Garter.
2. Etymology: from Latin Georgius, from Greek Georgios, "husbandman, farmer"; from ge-, "earth" + ergon, "work".
