In America, this name received a boost of popularity in 2000 when a character bearing it began appearing on the television series The West Wing.
Already an uncommon masculine name, it slowly grew in popularity for American girls beginning in 1978 after the start of the sitcom WKRP in Cincinnati, which featured a character with this name. Though it remained more common as a feminine name, it got a boost for boys in 1994 from another television character on the drama Party of Five. In the United Kingdom and Australia it has always been more popular for boys.
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.
