This name was borne by the heroine of Lewis Carroll's novels Alice's Adventures in Wonderland (1865) and Through the Looking Glass (1871).
In the Middle Ages this name was common in England due to the popularity of medieval tales about the Trojan War. It subsequently became rare, but was revived in the 20th century.
Already growing in popularity due to Australian model Elle Macpherson (1964-), this name received a boost in the United States after the release of the 2001 movie Legally Blonde featuring the main character Elle Woods. In the United Kingdom the name was already fairly common at the time the movie came out, and it actually started declining there shortly afterwards. A famous bearer is American actress Elle Fanning (1998-).
Jonah's story was popular in the Middle Ages, and the Hellenized form Jonas was occasionally used in England. The form Jonah did not become common until after the Protestant Reformation.
Though in use elsewhere in Europe, the name was very rare in the English-speaking world until the 19th century, when Queen Victoria began her long rule of Britain. She was named after her mother, who was of German royalty. Many geographic areas are named after the queen, including an Australian state and a Canadian city.
