As an English name, Zoe (sometimes with a diaeresis as Zoë) has only been in use since the 19th century. It has generally been more common among Eastern Christians (in various spellings).
This was the name of a 13th-century Italian saint who made clothes for the poor. As an English name, it has never been common.
The name was common in France during the Middle Ages, and was introduced from there to England, though it eventually became rare. Interest in it was revived by the character Melanie Wilkes from the novel Gone with the Wind (1936) and the subsequent movie adaptation (1939).
As a given name it was mostly masculine before 1940, but it rose in popularity as a name for girls during the 40s and 50s, probably due both to Grace Kelly (who married Prince Rainier III of Monaco in 1956) and a female character on the 1957 television series Bachelor Father [1]. By the end of the 1970s it was on the decline.
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.
After the Norman Conquest this name became common in England. It was revived in the 18th century, perhaps in part due to Matthew Prior's 1709 poem Henry and Emma [2]. It was also used by Jane Austen for the central character, the matchmaker Emma Woodhouse, in her novel Emma (1816).
In the United States, it was third in rank in 1880 (behind only the ubiquitous Mary and Anna). It declined steadily over the next century, beginning another rise in the 1980s and eventually becoming the most popular name for girls in 2008. At this time it also experienced similar levels of popularity elsewhere, including the United Kingdom (where it began rising a decade earlier), Germany, France, Italy, Spain, Scandinavia and the Netherlands. Famous bearers include the actresses Emma Thompson (1959-), Emma Stone (1988-) and Emma Watson (1990-).
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.
