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".
