A common theme with boy and unisex names is that once they become more popular for girls, they stop being used as boy names all together, often due to parents' fear of their sons being perceived as feminine. Other times, they come into popularity as boy names, lose popularity, and then make a comeback as a girl's name (like in the case of Evelyn). Some of these names are still completely usable for a boy, some are still more common for boys in some countries, and some you might get side-eyed for using but might still make for charming middle names.
- Quinn
Origin:
IrishMeaning:
"descendant of Conn, chief leader, intelligence"Description:
Quinn is an engaging Celtic surname that is still on the rise for girls but beginning to flag for boys. As a female name, Quinn is in the Top 100, used for over 3000 baby girls last year, but toward the bottom of the Top 500 for boys, given to 700 baby boys.
- Avery
Origin:
EnglishMeaning:
"ruler of the elves"Description:
Avery is a unisex name that is used four times as often today for girls as for boys. But while Avery's popularity is starting to soften for girls, it continues to get stronger for boys -- in keeping with our finding that gender neutral names are becoming more favored for boys than for girls.
- Morgan
Origin:
WelshMeaning:
"sea-born, sea-song or sea-circle"Description:
Morgan, once split evenly between the sexes, is a strong and attractive Welsh favorite, still a common boys’ name in Wales. Morgan is now more often a girls' name in the U.S. – about 2000 girls were given the name in one recent year, vs. 362 boys – though it's one of the most traditional unisex choices. Morgan was actually a Top 200 pick for boys in Victorian Britain!
- Riley
Origin:
English, IrishMeaning:
"rye clearing; courageous"Description:
Riley -- one of the most popular unisex names -- is trendier now for girls though for boys it's a classic, ALWAYS ranking in the US Top 1000.
- Florence
Origin:
English, French, LatinMeaning:
"flourishing"Description:
Florence is historically a unisex name, deriving both from Latin Florentius and Florentia. Although much more commonly feminine in modern times, it appeared in the US Top 1000 for boys until 1914.
- Emery
Origin:
English from GermanMeaning:
"industrious"Description:
Emery is one of the newly popular Em- names that has great potential, though right now for girls more than boys: it received a boost in 2009, a year after Angie Harmon and Jason Sehorn used it for one of their daughters.
- Ashley
Origin:
EnglishMeaning:
"dweller near the ash tree meadow"Description:
It may have peaked at #1 for girls in 1991 and 1992 in the US, but Ashley actually has a long history as a male given name, as evidenced by the sensitive Ashley Wilkes in Gone With the Wind. It's always been more popular for boys in England and Wales, where it currently ranks at #414.
- Reese
Origin:
Spelling variation of RhysDescription:
An Anglicized spelling of the Welsh Rhys, this traditional boys' name got a big boost for girls in the early 2000s, thanks to the high-profile Ms. Witherspoon (who was actually born Laura Jeanne Reese, her second middle being her mother's maiden name). This spelling has been on the decline for boys since 2003, possibly for the same reason, but remains a strong, simple choice which might pose fewer spelling and pronunciation issues outside of the UK than the Welsh original.
- Evelyn
Origin:
EnglishMeaning:
"desired; or water, island"Description:
Renowned English author Evelyn Waugh pronounced his name "EEV-lin" (fun fact: his first wife, also named Evelyn, was referred to as "She-velyn"). But "EV-uh-lin" also works, and is probably the most familiar pronunciation of the name today.
- Aubrey
Origin:
English from FrenchMeaning:
"elf ruler"Description:
Once a popular choice in for boys in the Middle Ages and again during the 19th century, Aubrey has mostly been used for girls in the US since the 1970's. With its arty, surname-y, and sophisticated feel, however, it is rising up the UK charts for both boys and girls.
- Blair
Origin:
ScottishMeaning:
"dweller on the plain"Description:
One of the first generation of cool surname names, now largely used for girls in the US, but still popular for boys in its native Scotland. A prominent association for Brits is former prime minister Tony Blair, who was leader at the time of the Iraq War.
- Madison
Origin:
EnglishMeaning:
"son of Matthew"Description:
Madison was at one time a strictly boys' presidential name, reaching as high as Number 311 at the end of the nineteenth century. That all changed in 1985 when it entered the girls' list, zooming up quickly until it reached the Number 2 spot, with more than 22,000 female babies given the name in 2001. As is so often the case, its use for boys has dropped precipitously.
- Meredith
Origin:
WelshMeaning:
"great ruler"Description:
Meredith has been considered primarily a girl's name since the fifties, before which it was more commonly used for boys. Comic actor Jay Mohr recently named his son Meredith, which might help it swing back into the blue column. The traditional Welsh pronunciation puts the stress on the middle syllable, making Red a cool nickname possibility.
- Harley
Origin:
EnglishMeaning:
"hare clearing"Description:
You can ride one, you can use it as a baby name – or, as is often the case, both! Harley is currently trending up for girls and down for boys in the US, although it remains predominantly masculine in the UK. A lesser-used -ley ending choice for boys, Harley has a current sound but an old-school biker appeal.
- Ariel
Origin:
HebrewMeaning:
"lion of God"Description:
Despite its distinguished pedigree and popularity in Israel, Disney's Little Mermaid cartoonized Ariel in the US, at least in some people's minds. But it was used for a male character in Shakespeare's The Tempest centuries ago.
- Jade
Origin:
EnglishMeaning:
"gemstone"Description:
When Jade first took off as a given name back in the 1970's, it was in fact considered unisex. It ranked in the US Top 1000 first for boys, then for girls, 7 years later. By the 80's however, Jade was more familiar as a girls' name and by the 2000's, it was gone from the charts for boys.
- Alexis
Origin:
GreekMeaning:
"defender"Description:
This name leapt into the female column via vixen Alexis Carrington on 'Dynasty" in the 1980s. It's more popular for girls, but it's still a widely used boys' names and is one of the most popular unisex names in the US today.
- Leslie
Origin:
ScottishMeaning:
"garden of holly"Description:
This Scottish place name and surname was more popular for boys in the US until the mid-1940s; in the UK, the Leslie spelling is predominantly masculine, with Lesley widely used as the feminine variant. Now ranking in the mid-400s for girls and not at all for boys in the US, it could be time to bring this smart, subtle nature name back, especially considering the current popularity of -ley names for both sexes.
- Monroe
Origin:
ScottishMeaning:
"mouth of the Roe river"Description:
Monroe is a presidential surname which feels fresher than Jackson, Lincoln and Taylor. Marilyn Monroe is a famous female namesake, but her smart Scottish surname feels equally usable for either sex. Plus, we think old man nickname Moe would sound both cool and adorable on a baby boy today!
- Vivian
Origin:
LatinMeaning:
"life"Description:
Deriving from the Roman cognomen Vivianus, Vivian was originally a masculine name, with Vivien being a feminine soundalike coined by Alfred Lord Tennyson for the Lady of the Lake in his famous poetic adaptation of the legend of King Arthur. It has since become a much more popular choice for girls in the US, but retains a refined British charm which sees it cropping up occasionally for boys in the Telegraph birth announcements.
