The post 11 Boys’ Names That Became Girls’ Names — and Never Went Back first appeared on Crafting Your Home.
A name can look as though it has always belonged to one gender. But naming history tells a different story. Several names many people now strongly associate with girls were once used for boys, sometimes for generations.
The shift rarely came from a single event. Names move through culture much like other trends: they are borrowed from surnames, popularized by books and films, influenced by famous people, and gradually associated with a new generation. Research on American naming patterns shows that these changes can be surprisingly durable.
The U.S. Social Security Administration (SSA), which publishes historical baby-name data going back to 1880, provides one of the clearest ways to see these changes. Its database records names separately for boys and girls, making it possible to track how a name’s gender distribution changes over time.
Ashley
Ashley is one of the clearest examples of a masculine-to-feminine shift. The name comes from an English surname and place name associated with an “ash tree clearing.” According to the historical reference compiled by Behind the Name, Ashley was more commonly given to boys in the United States until the 1960s. It later became predominantly feminine in American usage.
Popular culture also helped associate the name with males before its major shift. Margaret Mitchell used Ashley Wilkes as a male character in Gone with the Wind, published in 1936. The change that followed is particularly interesting because Ashley did not simply become unisex and stay that way. Its use increasingly concentrated among girls.
Leslie
Leslie has Scottish surname origins and was used as a given name from the 19th century onward. Its history is more complicated than the modern perception suggests. Behind the Name records Leslie as both masculine and feminine, while noting that in America it became more common as a feminine name after the 1940s.
Leslie is also specifically discussed in academic research into changing name patterns. The Poetics study found that names such as Leslie and Ashley were affected by a broader change in the appeal of names ending with the long “e” sound. In other words, their movement toward female use was not necessarily the result of parents simply deciding that a particular masculine name should become feminine. It was part of a larger change in naming taste.

Evelyn
Evelyn is a striking example because its modern identity differs so much from its earlier history. The name developed from an English surname connected with Aveline. According to Behind the Name, when Evelyn first came into use as a given name in the 17th century, it was more common for boys. Today, it is regarded as almost entirely feminine in English-language usage.
Its popularity also shows how dramatically a name can shift across generations. Evelyn was widely used in the early 20th century and later experienced a major revival. The SSA’s current data shows Evelyn among the leading girls’ names of 2020–2025, ranking ninth with 55,734 recorded births in those six years.
Kelly
Kelly has Irish roots and began as an anglicized form of the Irish name Ceallach and the surname Ó Ceallaigh. Its American naming history provides a particularly clear example of a name changing direction. Historical name research compiled by Behind the Name indicates that Kelly was mostly masculine in the United States before 1940, then became more popular among girls during the 1940s and 1950s. Grace Kelly’s fame and a female television character are cited as possible influences on that rise.
The important point is that cultural influence does not necessarily operate through a single celebrity. A famous person or fictional character can help make an existing name familiar, while broader naming preferences determine whether that familiarity lasts.
Beverly
Beverly began as an English surname derived from the name of a Yorkshire city. The underlying place name is associated with Old English elements referring to a beaver and a stream. According to Behind the Name, Beverly entered use as a masculine given name during the 19th century and later became common as an American feminine name, particularly after George Barr McCutcheon’s 1904 novel Beverly of Graustark. Its popularity peaked in the 1930s and subsequently declined.
Beverly illustrates another feature of naming history: a name can change gender association without remaining popular forever. Becoming strongly associated with girls does not guarantee a name will remain fashionable.

Madison
Madison is a more recent example, and its transformation is unusually well documented. The surname means “son of Matthew” or “son of Maud.” Despite that explicitly patronymic origin, Madison became a highly successful girls’ name in the United States near the end of the 20th century.
The turning point was the 1984 film Splash. In the movie, the mermaid character adopts the name Madison after seeing Madison Avenue. Behind the Name records that Madison was not commonly used as a feminine given name before the film and subsequently rose rapidly, reaching second place among U.S. girls’ names in 2001. This is a useful reminder that entertainment can introduce or accelerate a name, but popularity data is needed to establish whether the cultural exposure actually translated into widespread naming.
Lauren
Lauren is historically connected to Laurence, a name that was originally masculine. According to Behind the Name, Lauren was originally masculine. It became popular as a feminine name in part through actress Lauren Bacall, the stage name of Betty Joan Perske.
Lauren demonstrates how a name can acquire a new identity through a highly visible public figure. Once enough people encounter the name in a feminine context, later parents may hear it as feminine even if its earlier linguistic history points elsewhere.
Tracy
Tracy began as an English surname derived from a Norman French place name. It also appeared in masculine literary usage: Charles Dickens used Tracy for a male character in The Pickwick Papers in 1837. Its later history took a different turn. Behind the Name identifies Katharine Hepburn’s character Tracy Lord in the 1940 film The Philadelphia Story as a key moment in the name’s popularization as a feminine name.
Tracy therefore belongs to a wider group of names whose gender associations were influenced by fictional characters. But as with Madison and Kelly, view the cultural reference as an influence rather than automatically treating it as the sole cause of a naming shift.

Courtney
Courtney began as an aristocratic English surname. Its deeper origins trace to either the French place name Courtenay or a Norman nickname. In the United States, it was initially used as a relatively uncommon unisex name. It became more popular for girls in the 1960s and rose rapidly in the 1970s. Behind the Name notes that a television movie character may have contributed to this increase.
Courtney is particularly important to researchers because the name appears in the Poetics study of gendered naming. That research connects Courtney and Ashley to a broader change in the appeal of the long “e” sound in girls’ names.
Shannon
Shannon comes from the River Shannon in Ireland and ultimately connects to the Irish name Sionann. Unlike some of the names on this list, Shannon did not begin as a straightforwardly masculine personal name. It became common as an American given name after the 1940s and has been used for both boys and girls.
That makes Shannon a useful boundary case. Not every name commonly perceived as feminine today followed a simple “boys’ name, then girls’ name” path. Some names have always had periods of mixed use, with one gender eventually becoming dominant.
Vivian
Vivian has much older roots than most modern examples on this list. It comes from the Latin Vivianus, derived from vivus, meaning “alive.” The name has been used as a masculine English name since the Middle Ages. Behind the Name also records its modern feminine use and distinguishes it from related forms such as Vivien and Vivienne.
This is another reminder that naming history cannot always be reduced to a single switch from masculine to feminine. Names can have parallel traditions in different languages and periods, with their perceived gender shifting with culture and time.
Key Takeaways
The history of baby names reminds us that ordinary people constantly reshape language.
Ashley did not become feminine because its spelling suddenly changed. Madison did not become popular because its original meaning changed. Evelyn did not lose its earlier masculine history. Instead, generations of parents encountered these names in new contexts and gradually attached new associations to them.
The result is a fascinating cultural record. A name that once sounded distinctly masculine can eventually sound unmistakably feminine to a later generation. And, as the research shows, that transformation is not random: changes in sound, spelling, popular culture, and naming taste can all contribute.
So when a familiar girls’ name seems as though it could never have belonged to a boy, its history may tell a very different story.
