Names That Changed Gender Popularity Over Time

Here’s a fun fact that might catch you off guard — Ashley was once a 100% boys’ name. Yes, the same Ashley you probably associate with girls’ classrooms and sorority houses was originally given almost exclusively to boys in the early 1900s. By the 1990s? It was the #1 girls’ name in America.

Names don’t stay in one lane. They drift, they shift, and sometimes they completely flip from one gender to another. A name your grandfather wore proudly might now sit on a baby girl’s birth certificate. And honestly, this pattern isn’t new — it’s been happening for centuries.

If you’re a parent trying to pick a name, or you’re just curious about why your “manly” name is now trending for girls, you’re in the right place. Let’s unpack the fascinating stories behind names that changed gender popularity over time — the why, the when, and the real data behind these shifts.

Why Do Names Switch Genders in the First Place?

Before we get into specific names, let’s understand the pattern. Names don’t just randomly wake up one morning and decide to change teams. There are real sociological forces at work.

The “Trickle-Down” Effect

Researchers like sociologist Stanley Lieberson have studied this for decades. The pattern almost always goes in one direction: from masculine to feminine. A name starts as a boys’ name, then parents start giving it to girls (often because it sounds “strong” or “distinguished”), and once enough girls carry the name, boys abandon it.

Why? There’s an unfortunate cultural bias. Parents often feel comfortable giving a girl a “boy-ish” name because it feels empowering. But the reverse? Giving a boy a “girly” name? Most parents resist that. So once a name tips toward feminine use, boys almost never reclaim it.

Pop Culture and Celebrity Influence

A single movie, TV show, or famous person can shift a name’s gender perception almost overnight. One hit character on a popular show, and suddenly thousands of parents are writing that name on birth certificates — sometimes for the opposite gender than what history intended.

The “Uniqueness” Chase

Parents constantly hunt for names that feel fresh and different. Borrowing a traditionally male name for a girl (or, less commonly, the reverse) feels like a creative choice. The irony? Once enough parents have the same “creative” idea, the name shifts entirely.

The Most Famous Gender-Switching Names in History

Let’s look at specific names — backed by U.S. Social Security Administration (SSA) data — that made the biggest jumps across gender lines.

Ashley: The Poster Child of Gender Switching

Originally: A boys’ name, derived from Old English meaning “ash tree clearing.”

The timeline:

• Pre-1960s: Almost exclusively male. Think Ashley Wilkes from Gone with the Wind (1939) — a Southern gentleman.
• 1970s–1980s: Started appearing on girls’ lists, partly inspired by a character on the soap opera The Young and the Restless.
• 1991–1992: Became the #1 girls’ name in America according to SSA records.
• 2020s: Almost zero boys named Ashley. The switch is complete.

Did You Know? In the UK, Ashley still holds some male usage, but in the US, it’s become nearly 100% feminine.

Lindsay/Lindsey: A Complete Flip

Originally: A Scottish surname turned boys’ first name.

The timeline:

• 1940s–1960s: Predominantly male. Lindsay Nelson was a famous male sportscaster.
• 1970s–1980s: Actress Lindsay Wagner (The Bionic Woman) popularized it for girls.
• 1990s–2000s: Lindsay Lohan sealed the deal. The name became almost entirely feminine.

Quick Fact: By 2010, fewer than 10 baby boys per year were named Lindsay in the entire United States.

Meredith: From Welsh Warrior to Modern Woman

You probably think of Meredith Grey from Grey’s Anatomy. But Meredith comes from the Welsh name Maredudd, meaning “great lord” — about as masculine as it gets.

• Pre-1900s: A male name used across Wales and England.
• 1910s–1940s: Began appearing for girls in the US.
• 1960s onward: Solidly feminine. Very few boys receive this name today.

Courtney: Gone in a Generation

Originally: A Norman French surname meaning “short nose” (not exactly glamorous, but it was a strong male name).

• 1950s–1960s: Given to boys regularly.
• 1970s–1980s: Parents started using it for girls, attracted by its sophisticated sound.
• 1990s: Courtney Cox and Courtney Love made it undeniably feminine.
• Today: Almost exclusively a girls’ name.

Beverly: From a Boys’ Name to Your Grandmother’s Name

This one surprises people. Beverly was a boys’ name in the early 1900s, derived from an English place name meaning “beaver stream.”

• 1920s: The novel Beverly of Graustark featured a male protagonist named Beverly, but readers assumed the character was female.
• 1930s–1940s: Girls took over the name rapidly.
• 1950s: Beverly peaked for girls at #14 on the SSA charts.
• Today: It’s considered a dated women’s name. The male version has completely vanished.

Shannon: The River Name That Crossed Over

Named after Ireland’s River Shannon, this was originally a boys’ name.

• 1940s–1950s: Used for boys, especially in Irish-American families.
• 1960s–1970s: Became hugely popular for girls.
• 1976: Hit #17 on the girls’ chart.
• Today: Primarily feminine, though some male Shannons still exist in Ireland.

Names Currently in the Middle of a Gender Shift

Some names are switching right now — you can watch it happen in real time through SSA data and name popularity trends.

James: Girls Named James?

This one’s controversial. James has been a top-10 boys’ name for over a century. But in recent years, celebrities like Ryan Reynolds and Blake Lively named their daughter James (born 2014). Usage for girls is still tiny compared to boys, but it’s growing.

Pro Tip: Just because a celebrity uses a traditionally male name for a girl doesn’t mean it’ll fully switch. James has too much male history and current popularity to flip anytime soon. But it could become gender-neutral over several decades.

Charlie: Already Halfway There

Charlie used to be a boys’ nickname (short for Charles). Now it’s climbing girls’ charts rapidly.

• 2005: Barely registered for girls.
• 2020: Entered the top 150 for girls in the US.
• 2024–2025: Still rising for both genders, making it a true gender-neutral trending name.

Avery: The Quiet Switch

Avery was a boys’ name through the mid-1990s. Then something shifted.

• 1990: Ranked around #300 for boys, barely used for girls.
• 2000: Started appearing on girls’ lists.
• 2012: Reached the top 15 for girls while dropping below #200 for boys.
• 2025: Firmly perceived as a girls’ name by most American parents, though some boys still receive it.

Riley: Tipping Point Reached

An Irish surname meaning “courageous,” Riley followed the classic pattern.

• 1990s: Top 100 for boys.
• 2000s: Appeared on girls’ lists.
• 2016: Hit #25 for girls, surpassing its boys’ ranking.
• Today: More girls than boys are named Riley in the US.

The Rare Reverse: Names That Went From Feminine to Masculine

Remember how I said names almost always move from male to female? There are a handful of exceptions — and they’re genuinely rare.

Allison/Alison

This might surprise you. Alison was actually a medieval boys’ name — a diminutive of Alice (which was itself originally male in some early forms). It became feminine by the 1400s, making this one of the oldest gender switches on record.

Alexis

In most of the world, Alexis is still a boys’ name. In Greece, France, and much of Europe, Alexis is solidly male. But in the US, the TV show Dynasty (1981) featured a powerful female character named Alexis Carrington (played by Joan Collins), and the name shifted dramatically to the girls’ side in America.

Quick Fact: By 2000, over 90% of American babies named Alexis were girls, while in France, over 90% were boys. Same name, completely opposite gender associations depending on the country.

What Does the Data Actually Tell Us?

Let’s look at the bigger picture using SSA records, which track every name given to American babies since 1880.

The Numbers Behind the Pattern

• Over 50 names have made a significant gender switch since 1880 in the US.
• About 90% of those switches went from male to female.
• The average “tipping point” — where more girls than boys receive the name — takes about 15–20 years from when girls start using it.
• Once a name tips past 60% female usage, boys almost never come back to it.

A Decade-by-Decade View

Names don’t switch in isolation. They follow broader cultural patterns. You can explore this further through most popular names by decade from the 1950s to 2020s.

The pace has accelerated. More names switch faster now, partly because of social media’s influence on baby name choices.

Myths and Misconceptions About Gender-Switching Names

Myth #1: “Gender-Neutral Names Have Always Existed”

Reality: True gender-neutral names (ones that stay balanced between boys and girls for generations) are extremely rare. Most names that appear neutral are actually in transit from one gender to the other. They just happen to be at the 50/50 point when you’re looking.

Myth #2: “Boys’ Names Become Girls’ Names Because of Feminism”

Reality: This pattern existed long before modern feminism. Shirley switched in the 1930s. Beverly in the 1920s. The driving force is more about phonetics and naming aesthetics than political movements. Parents choose names that sound right to them, and cultural associations shift over time.

Myth #3: “Once a Name Switches, It’s Gone Forever”

Reality: Some names do make partial comebacks. Leslie and Dana still get occasional male use. And the trend of old-fashioned names making a comeback means a once-switched name could potentially return, though full reversals haven’t happened yet in recorded data.

Myth #4: “This Only Happens in English-Speaking Countries”

Reality: While the pattern is most dramatic in the US, UK, and Australia, other cultures experience name-gender shifts too. Andrea is male in Italy but female in the US. Nikita is male in Russia but perceived as female in Western countries. The psychology behind how we perceive names plays a big role here.

What Should Parents Consider?

If you’re choosing a name for your baby, this history matters — especially if you care about how the name might be perceived 20 or 30 years from now.

Practical Tips for Parents

Warning ⚠️

There’s no “safe” prediction. Nobody in 1950 would’ve guessed that Ashley would become the #1 girls’ name. Trends are observable in hindsight, but predicting which specific name will switch next is genuinely difficult. Even AI-based baby name prediction tools can only give probabilities, not certainties.

Names to Watch: Potential Future Switches

Based on current SSA trends and why some names suddenly become popular, here are names showing early signs of a gender shift:

• Elliott: Traditionally male, but entering girls’ charts. Usage for girls grew by over 300% between 2010 and 2023.
• Emerson: Originally male (think Ralph Waldo Emerson). Now used more for girls than boys in several states.
• Rowan: Still predominantly male, but girls’ usage is climbing steadily.
• Sage: Nearly split 50/50 right now. Could tip either way.
• Sutton: Historically a boys’ surname-name, now trending for girls thanks to TV personality Sutton Stracke.

FAQ Section

Do names only switch from boys to girls, or can it go both ways?

Almost every documented name-gender switch in the US has gone from male to female. Switches from female to male are extremely rare. The reason is cultural: parents see giving a girl a “strong” male name as positive, but giving a boy a “feminine” name still carries social stigma for many families. So once a name tips toward female use, boys drop it — and they almost never pick it back up.

Can a gender-switched name hurt my child?

Research from studies published in the Journal of Experimental Social Psychology and similar publications shows that names do carry associations. A boy named Ashley or Courtney in 2025 might face questions or assumptions about his name. The impact varies widely — some kids embrace a unique name situation, while others find it frustrating. Your child’s personality, your community, and your family’s attitude all play roles. If you’re curious about how names affect life outcomes, explore whether your name can affect your career.

What’s the fastest a name has ever switched genders?

Shirley is often cited as one of the fastest switches. Before the 1935 film Curly Top starring Shirley Temple, the name was predominantly male. Within just 10 years, it became overwhelmingly female. By 1940, it was a top-10 girls’ name, and virtually no boys received it. That’s a near-complete flip in a single decade — driven almost entirely by one child star’s fame.

Are there any truly permanent gender-neutral names?

Very few names have stayed genuinely balanced between genders for more than 30 years. The ones that come closest include Casey, Jessie, and Jackie, which have maintained some level of dual-gender use for decades. But even these tend to lean one direction depending on the era. True permanent neutrality is remarkably hard for a name to maintain.

Your Name Tells a Bigger Story Than You Think

Every name that switches gender carries a piece of cultural history with it. Shirley tells the story of Hollywood’s golden age. Ashley reflects 1980s American family values. Riley captures the 2010s trend toward breaking traditional gender boxes.

If you’re picking a name for your child, knowing this history gives you real power. You’re not just choosing a label — you’re choosing a trajectory. Check how many people already share your chosen name to get a sense of where it stands right now.

And if your own name happens to be one that switched? You’re carrying a small, fascinating piece of social evolution with you every single day. That’s a pretty cool story to tell at parties — or, you know, over chai. ☕
