It has occasionally been used as an English given name since the 16th century. It was moderately popular in the 1940s, but had a more notable upswing in the early 2000s. This may have been inspired by the Spanish actress Penélope Cruz (1974-), who gained prominence in English-language movies at that time. It was already rapidly rising when celebrities Kourtney Kardashian and Scott Disick gave it to their baby daughter in 2012.
Although this name was borne by several early saints, including a pope, it was rare during the Middle Ages. It was revived in Italy and France during the Renaissance, and was subsequently imported to England.
This name began rising on the American popularity charts in 2008, slowly until 2012 and then rapidly after that. This might have been triggered by the folk band Everly (not associated with the Everly Brothers), which had music featured on the television series One Tree Hill in that period. It also might have simply been inspired by similar-sounding names like Everett, Evelyn and Beverly.
In modern Irish this name is properly spelled Éadaoin.
This name was fairly popular at the end of the 19th century and beginning of the 20th. The American author F. Scott Fitzgerald used it for the character of Daisy Buchanan in The Great Gatsby (1925). The Walt Disney cartoon character Daisy Duck was created in 1940 as the girlfriend of Donald Duck. It was at a low in popularity in the United States in the 1970s when it got a small boost from a character on the television series The Dukes of Hazzard in 1979.
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.
A known bearer of this name was Altaluna della Scala, daughter of Mastino II della Scala, a 14th-cenutry lord of Verona, sister of Viridis and wife of Louis V, Duke of Bavaria.
Whether Altalune, the name Uma Thurman gave her daughter born in 2012, is a medieval variant of this name, is still debated.
The name has been used by kings of Scotland, Poland and Yugoslavia, emperors of Russia, and eight popes. Other notable bearers include English poet Alexander Pope (1688-1744), American statesman Alexander Hamilton (1755-1804), Scottish-Canadian explorer Alexander MacKenzie (1764-1820), Russian poet Alexander Pushkin (1799-1837), and Alexander Graham Bell (1847-1922), the Scottish-Canadian-American inventor of the telephone.
