As an English name, Chloe has been in use since the Protestant Reformation. It started getting more popular in the 1980s in the United Kingdom and then the United States. It was the most popular name for girls in England and Wales from 1997 to 2002. This is one of the few English-language names that is often written with a diaeresis, as Chloë.
Famous bearers include the Welsh poet Dylan Thomas (1914-1953) and the American musician Bob Dylan (1941-), real name Robert Zimmerman, who took his stage surname from the poet's given name. Due to those two bearers, use of the name has spread outside of Wales in the last half of the 20th century. It received a further boost in popularity in the 1990s due to a character on the television series Beverly Hills 90210.
Famous bearers include the German intellectual Max Weber (1864-1920) and the German physicist Max Planck (1858-1947). This name is also borne by the title character in the Mad Max series of movies, starting 1979.
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).
