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).
This name also appears in southern Germanic legends (often spelled Perchta or Berchta) belonging to a goddess of animals and weaving.
As a given name, Diana has been regularly used since the Renaissance. It became more common in the English-speaking world following Walter Scott's novel Rob Roy (1817), which featured a character named Diana Vernon. It also appeared in George Meredith's novel Diana of the Crossways (1885). A notable bearer was the British royal Diana Spencer (1961-1997), the Princess of Wales.
As a rarer (but older) masculine name it is probably derived from a surname: see Fay 1 or Fay 2.
This name has been borne by six kings of Sweden, including the 16th-century Gustav I Vasa. Another notable bearer was the Austrian painter Gustav Klimt (1862-1918).
Though it has never been popular in the English-speaking world among Christians, it has historically been a common name for Jews, who have used it as an Americanized form of names such as Isaac, Israel and Isaiah.
As an English name, Laura has been used since the 13th century. Famous bearers include Laura Secord (1775-1868), a Canadian heroine during the War of 1812, and Laura Ingalls Wilder (1867-1957), an American author who wrote the Little House on the Prairie series of novels.
Although this name was used by Jews in the Middle Ages, it was not typical as an English Christian name until after the Protestant Reformation, being common among the Puritans.
