In the English-speaking world this name is more commonly given to girls. This is due to the American actress Alexis Smith (1921-1993), who began appearing in movies in the early 1940s. It got a boost in popularity in the 1980s from a character on the soap opera Dynasty.
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.
This name died out after the Middle Ages, but was revived in the 19th century. In America and other countries it became fairly popular in the second half of the 20th century. A famous bearer of the surname is former basketball star Michael Jordan (1963-).
Before 1980, this was an uncommon masculine name in America. During the 1980s and 90s this name steadily increased in popularity for both boys and girls, and from 2003 onwards it has been more common for girls in the United States. Elsewhere in the English-speaking world, such as the United Kingdom and Australia, it has remained largely masculine.
Very rare as an American given name before 1980, it increased in popularity in the 1980s and 90s. It got a boost in 2004 after the debut of the television series Lost, which featured a character by this name.
Its modern use as a feminine name may have been influenced by the British-American author Taylor Caldwell (1900-1985). Since 1990 it has been more popular for girls in the United States. Other England-speaking regions have followed suit, with the exception of England and Wales where it is still slightly more popular for boys. Its popularity peaked in America the mid-1990s for both genders, ranked sixth for girls and 51st for boys. A famous bearer is the American musician Taylor Swift (1989-).
