As a Christian given name, Salome has been in occasional use since the Protestant Reformation. This was due to a second person of this name in the New Testament: one of the women who witnessed the crucifixion and later discovered that Jesus' tomb was empty. It is used in Georgia due to the 4th-century Salome of Ujarma, who is considered a saint in the Georgian Church.
It has been used as a Christian given name in the English-speaking world since the Protestant Reformation. A famous bearer was Nathan Hale (1755-1776), an American spy executed by the British during the American Revolution.
As an English name, Jonathan did not become common until after the Protestant Reformation. A famous bearer was the Anglo-Irish satirist Jonathan Swift (1667-1745), who wrote Gulliver's Travels and other works.
This is one of the few Old English names to be used throughout Europe (in various spellings). A famous bearer was the British composer Edward Elgar (1857-1934). It was also used by author Charlotte Brontë for the character Edward Rochester, the main love interest of the title character in her novel Jane Eyre (1847).
In the English-speaking world this name is more commonly given to girls. This is due to the American actress Alexis Smith (1921-1993), who began appearing in movies in the early 1940s. It got a boost in popularity in the 1980s from a character on the soap opera Dynasty.
