Here’s a fun party trick: take any name that sounds hopelessly dated right now—the kind of name that makes you picture someone’s great-aunt who smells like talcum powder and has opinions about Roosevelt—and wait. Give it about a century. Suddenly that musty old name starts sounding… kind of cool? Kind of fresh? Kind of like something a Brooklyn creative director would name their kid?
Welcome to the 100-Year Rule, and welcome to the 1920s revival that’s already quietly underway.
What Is the 100-Year Rule?
The 100-Year Rule is exactly what it sounds like: names tend to cycle back into fashion about a century after their peak popularity. It takes roughly three generations for a name to shake off its “old person” associations and start sounding vintage-cool instead of vintage-dusty.
Think about it. In the 1990s, nobody was naming their baby Evelyn or Hazel—those were grandma names. But their grandmas were born in the 1920s, which means those names hit their 100-year mark right around… now. And sure enough, Evelyn is currently sitting in the Top 10, and Hazel cracked the Top 30.
The math works. The psychology works. And if you want to get ahead of the curve instead of following it, you need to start looking at what was popular in the 1920s that hasn’t come back yet. That’s where it gets interesting.
The Names That Already Made It Back
Before we dig into the undiscovered gems, let’s acknowledge the 1920s names that have already completed their journey from dated to beloved. These are the proof of concept:
- For girls: Evelyn, Hazel, Eleanor, Alice, Violet, Ruby, Clara, Stella, Josephine, Lillian, Elsie, Ada
- For boys: Theodore, Henry, Arthur, Leo, Oscar, Felix, Oliver, Jack
Eleanor and Josephine in particular have that letter-writing, linen-wearing elegance that’s fully mainstream now. They sound exactly like names that Wear Linen and Write Letters by Hand.
The question is: what’s next?
1920s Girl Names Poised for Comeback
These are the names sitting right at the edge. All of them have that 1920s quality—a certain strength wrapped in softness, a no-nonsense femininity—that feels right for this moment.
- Mabel: It’s got the same cozy, slightly quirky energy as Hazel, and it means “lovable.” The fact that it sounds like a grandma who makes really good pie is now a feature, not a bug. It has that grounded feel of names that sound like they grew up on a Porch Swing.
- Beatrice: It means “she who brings happiness,” it’s got literary cred, and the nickname Bea is genuinely adorable. If you’re into Literary Baby Names, Beatrice delivers on multiple levels.
- Vera: Means “faith” in Russian and “true” in Latin. It’s short, strong, and feels like a woman who runs her own business and doesn’t suffer fools.
- Lucille: It combines the light-meaning of Lucy (see our list of Names That Mean Light (But Don’t Scream It)) with more substance and formality.
- June: One syllable, clean as a whistle, and has that midcentury charm without the fussiness. It works as a classic name but still feels current.
- Pearl: A gem name without the flash of Ruby. Pearl is quietly luminous, like the thing itself. Bonus: it works beautifully in a sibling set with other nature names, such as those on our list of Bird Names for Babies.
- Iris: It’s a flower name, a goddess name (Iris was the Greek goddess of rainbows), and a grandma name all at once. That’s efficient. If you’re into botanical names or Greek Mythology Names, Iris covers both bases.
- Sylvia: Means “from the forest,” which gives it some Landscape Name energy. It’s distinguished and slightly bohemian.
- Florence: It’s got the place-name appeal (Florence, Italy), the nickname appeal (Flo, Flossie, Flora), and the meaning appeal (“flourishing”).
1920s Boy Names Poised for Comeback
Boy names cycle more slowly, but the 1920s had plenty of boys’ names that are ripe for rediscovery.
- Walter: The sleeper hit. It’s got the same old-man-cool as Theodore and Arthur, and that meaning of “ruler of the army” sounds commanding without being aggressive.
- Eugene: A risk. It’s deeply uncool right now, but it means “well-born.” Eugene is a world away from names that sound like they belong in a Sci-Fi Love Story.
- Chester: Means “fortress” and sounds like a man who knows how to fix things. The nickname Chet has definite cool-dad energy.
- Ralph: One syllable, strong, and it means “wolf counsel,” very Game of Thrones.
- Vernon: It means “alder tree,” which gives it some nature cred.
- Floyd: It means “gray-haired,” but the sound is great—that “oy” in the middle, the strong ending. It’s never going to be Top 100, unlike some of the more basic 90s Names Making a Sneaky Comeback.
- Ernest: Ernest has Hemingway. Ernest has Oscar Wilde’s play. Ernest has the meaning “serious, resolute.” It’s got all the ingredients—Powerful Meanings, literary cred, vintage charm—but is still waiting for its moment.
- Louis: It’s classic French, it’s been the name of approximately one million kings, and it has the friendly nickname Lou. It’s not as out there as some of the others on this list, but it deserves to be more popular.
How to Use the 100-Year Rule
If you’re intrigued by this concept and want to apply it yourself, here’s the framework:
- Find a list of popular names from 100 years before your baby’s birth year.
- Identify names that are currently unused or rare. If it’s already in the Top 200, you’ve missed the wave.
- Test the name for wearability. Say it out loud. Put it on a resume.
- Consider the nickname. Part of why names like Theodore and Eleanor came back strong is that Theo and Ellie are great nicknames.
- Trust your gut.
The 100-Year Rule suggests that the names our great-grandparents loved will eventually be the names our grandchildren love too. It’s a cycle, not a line.
Pair It Right
If you’re going with a 1920s revival name, think about how it pairs with a middle name. A name like Iris pairs beautifully with a global middle name like Mahina from our Names That Mean Moon in 5 Languages list.
