This was a top-ten name in France for most of the 1940s and 50s, while in Germany it was the most popular name for several years in the 1970s and 80s. In the United States it peaked in the late 1990s and early 2000s. Famous bearers include Hans Christian Andersen (1805-1875), the Danish author of such fairy tales as The Ugly Duckling and The Emperor's New Clothes, and the French fashion designer Christian Dior (1905-1957).
Eli has been used as an English Christian given name since the Protestant Reformation. A notable bearer was the American inventor of the cotton gin Eli Whitney (1765-1825).
Because Elijah was a popular figure in medieval tales, and because his name was borne by a few early saints (who are usually known by the Latin form Elias), the name came into general use during the Middle Ages. In medieval England it was usually spelled Elis. It died out there by the 16th century, but it was revived by the Puritans in the form Elijah after the Protestant Reformation. The name became popular during the 1990s and 2000s, especially in America where it broke into the top ten in 2016.
The name was common among Jews in the Middle Ages, but it was not generally used as a Christian name in the English-speaking world until after the Protestant Reformation. It was moderately popular in the first half of the 20th century, but starting in the 1960s it steadily rose, reaching highs in the 1980s and 90s. The character Rachel Green on the American sitcom Friends (1994-2004) may have only helped delay its downswing.
Notable bearers include American conservationist Rachel Carson (1907-1964), British actress Rachel Weisz (1970-), and Canadian actress Rachel McAdams (1978-).
