As an English name it can also derive from the month of August, which was named for the Roman emperor Augustus.
As a given name, it was used on the American sitcom Murphy Brown (1988-1998) for both the mother and son of the main character. By 1998 it was more popular as a name for girls in the United States, perhaps further inspired by a character from the movie Jerry Maguire (1996).
This name was fairly common in France, England and the United States in the early 20th century. It became quite popular in France and England at the end of the 20th century, just when it was at a low point in the United States. It quickly climbed the American charts and entered the top ten in 2014.
This name got more popular in the early 1980s, then got a boost in 1990 when it was used by the main character in the movie Days of Thunder.
This name was very popular in the English-speaking world at the end of the 19th century. Though it declined in use over the next 100 years, it staged a successful comeback at the end of the 20th century. The American sitcom Will and Grace (1998-2006) may have helped, though the name was already strongly rising when it premiered. It was the top name for girls in England and Wales in 2006.
As an English Christian name, Levi came into use after the Protestant Reformation.
As an English Christian name, Noah has been used since the Protestant Reformation, being common among the Puritans. In the United States it was not overly popular in the 19th and 20th centuries, but it began slowly growing in the 1970s. Starting 1994 it increased rapidly — this was when actor Noah Wyle (1971-) began starring on the television series ER. A further boost in 2004 from the main character in the movie The Notebook helped it eventually become the most popular name for boys in America between 2013 and 2016. At the same time it has also been heavily used in other English-speaking countries, as well as Germany, the Netherlands, Scandinavia and France.
A famous bearer was the American lexicographer Noah Webster (1758-1843).
