Due to the saint's renown, the name became common in the Christian world (in various spellings). As an English name, Luke has been in use since the 12th century alongside the Latin form Lucas. Both forms became popular throughout the English-speaking world towards the end of the 20th century. A famous fictional bearer was the hero Luke Skywalker from the Star Wars movies, beginning in 1977.
This name became very popular in the second half of the 20th century. It reached the top ten names for boys in France (by 1997), Belgium (1998), Denmark (2003), Canada (2008), the Netherlands (2009), New Zealand (2009), Australia (2010), Scotland (2013), Spain (2015) and the United States (2018).
American writers Jack London (1876-1916) and Jack Kerouac (1922-1969) were two famous bearers of this name. It is also borne by the actor Jack Nicholson (1937-) and the golfer Jack Nicklaus (1940-). Apart from Nicklaus, none of these famous bearers were given the name Jack at birth.
In the United Kingdom this form has been bestowed more frequently than John since the 1990s, being the most popular name for boys from 1996 to 2008.
Gawain was a popular hero in medieval tales such as those by Chrétien de Troyes, where his name appears in the French form Gauvain or Gauvains. He is the main character of the 14th-century anonymous poem Sir Gawain and the Green Knight, in which he accepts a potentially fatal challenge from the mysterious Green Knight.
Arthur is the name of the central character in Arthurian legend, a 6th-century king of the Britons who resisted Saxon invaders. He may or may not have been based on a real person. He first appears in Welsh poems and chronicles (perhaps briefly in the 7th-century poem Y Gododdin and more definitively and extensively in the 9th-century History of the Britons [1]). However, his character was not developed until the chronicles of the 12th-century Geoffrey of Monmouth [2]. His tales were later taken up and expanded by French and English writers.
The name came into general use in England in the Middle Ages due to the prevalence of Arthurian romances, and it enjoyed a surge of popularity in the 19th century. Famous bearers include German philosopher Arthur Schopenhauer (1788-1860), mystery author and Sherlock Holmes creator Arthur Conan Doyle (1859-1930), and science-fiction author Arthur C. Clarke (1917-2008).
