Have you ever noticed how your grandmother’s name might suddenly be the coolest thing to call a newborn? There’s this idea floating around that baby names cycle back into popularity every 100 years or so – the so-called “100 Year Rule.” I’ve been fascinated by this concept for a while now, especially when I hear about babies named Florence or Theodore at the local playground.
Is this really a thing, though? Do names actually follow a century-long pattern before becoming fashionable again? Let’s dive into this intriguing naming phenomenon and see if there’s any truth behind it.
What Exactly Is the 100 Year Rule?
The 100 Year Rule suggests that baby names follow a predictable cycle, falling out of favor for about three generations (roughly 100 years) before making a comeback. According to this theory, the names that were popular during your great-grandparents’ era are likely to be trending again for today’s babies.

Think about it – names that sound “old-fashioned” to our parents often sound charming and vintage to us. Names that were common in the 1920s might feel fresh and distinctive in the 2020s, while names from the 1970s might still feel a bit dated or “middle-aged.”
I remember my mother wrinkling her nose when I mentioned loving the name Hazel for a future daughter. “That’s an old lady name!” she said. But to me, it sounded fresh, nature-inspired, and distinctive. This generational disconnect is exactly what the 100 Year Rule tries to explain.
Testing the Theory: Do Names Really Come Back Every Century?
To see if this theory holds water, let’s look at some popular names from the early 1900s and compare them to trending names today:
Popular Girls’ Names from the 1910s-1920s:
1. Mary
2. Helen
3. Dorothy
4. Margaret
5. Ruth
6. Mildred
7. Florence
8. Elizabeth
9. Anna
10. Ethel
Popular Boys’ Names from the 1910s-1920s:
1. John
2. William
3. James
4. Robert
5. Joseph
6. Charles
7. George
8. Edward
9. Frank
10. Thomas
Now, if we look at some of today’s trending names, we do see some interesting overlaps. Names like William, James, Thomas, and Elizabeth have remained fairly steady in popularity over the decades, but others like Florence, Ruth, George, and Edward have indeed experienced a resurgence after falling out of favor for decades.
The theory seems to have some merit. Names like Hazel, Violet, Oliver, Theodore, and Henry – all popular in the early 1900s – are now among the fastest-rising baby names in recent years. But the pattern isn’t quite as neat as a perfect 100-year cycle would suggest.
The Psychology Behind the Cycle
Why would names follow this pattern? There are actually several interesting psychological and sociological factors at play:
First, there’s the “grandparent avoidance” phenomenon. Parents often avoid names associated with their parents’ generation (which might feel middle-aged or ordinary), but may be drawn to names from their grandparents’ or great-grandparents’ generation (which feel vintage and distinctive).
I think there’s also something about the human desire for both novelty and tradition. We want names that feel special but not bizarre, familiar but not overused. Reviving names from several generations back satisfies both these needs perfectly.
Another factor is that by the time a name has been out of fashion for about 80-100 years, most of the associations with “old people” have faded. When today’s parents hear “Evelyn” or “Theodore,” they likely don’t have immediate associations with elderly individuals, making these names feel fresh again.
Case Studies: Names That Follow the Rule
Some names demonstrate the 100 Year Rule remarkably well. Let’s look at a few examples:
Emma: This name was extremely popular in the late 19th century, declined significantly by mid-20th century, and then began a remarkable comeback in the 1990s and 2000s. By 2018, it was the #1 name for girls in the United States – almost exactly 100 years after its previous peak.
Theodore: Popular in the early 1900s, this name fell out of the top 100 by the 1950s. Now it’s surging again, ranking #23 in 2021, with the nickname “Theo” becoming especially fashionable.
Ruby: A top 20 name in the 1900s-1910s, Ruby nearly disappeared from the charts by the 1970s. It began climbing again in the 2000s and has been in the top 100 since 2003.
Arthur: This classic name was a top 20 choice in the early 1900s, fell sharply mid-century, and has recently returned to the top 100 in both the US and UK.
Perhaps the most striking examples are found in girls’ names ending with “-ie” or “-a” sounds:
Girls’ names with vintage appeal making comebacks:
1. Millie
2. Elsie
3. Sadie
4. Clara
5. Cora
6. Nora
7. Ada
8. Stella
9. Hazel
10. Evelyn
Exceptions to the Rule
While the pattern holds for many names, it’s definitely not universal. Some names from 100 years ago haven’t made a significant comeback:
Names from the 1920s still waiting for their revival:
1. Mildred
2. Gladys
3. Bertha
4. Gertrude
5. Clarence
6. Harold
7. Herbert
8. Clifford
And some modern popular names weren’t particularly common 100 years ago:
Modern names without early 1900s precedent:
1. Jayden
2. Aiden
3. Madison
4. Addison
5. Harper
6. Skylar
This suggests that while the 100 Year Rule captures something real about naming patterns, it’s just one of many factors influencing name trends.
Is It Really Exactly 100 Years?
Here’s where things get a bit fuzzy. When we look closely at the data, the cycle isn’t precisely 100 years. Some names come back in 80 years, others might take 120. And the comeback isn’t always to the same level of popularity as before.
For example, names like Sophia and Olivia are much more popular today than they were in the 1920s. Meanwhile, Mary – the undisputed #1 name for decades – has fallen much further than the 100 Year Rule would predict.
I think it’s more accurate to say there’s a general 3-4 generation cycle (roughly 80-120 years) where names tend to fade and potentially return, rather than a precise century-long pattern.
Modern Acceleration: Is the Cycle Speeding Up?
Interestingly, in our internet-connected world with rapid information sharing, some name cycles seem to be accelerating. Names can rise and fall faster than ever before.
Jessica, Jennifer, and Amanda were huge in the 1980s-90s but have already declined dramatically – much faster than historical patterns would suggest. Similarly, names like Brittany and Tiffany have fallen quickly and show little sign of imminent revival.
The question is whether these names will return to popularity in less than 100 years, or if they’ll follow the traditional timeline. Only time will tell, but my guess is that certain distinctly time-stamped names might actually take longer than 100 years to shed their generational associations.
Using the 100 Year Rule to Predict Future Trends
If there’s some truth to the 100 Year Rule, can we use it to predict which names might become popular in the coming decade?
Looking at popular names from the 1930s, we might expect these names to begin trending soon (if they haven’t already):
Girls’ names potentially due for revival:
1. Barbara
2. Shirley
3. Patricia
4. Joan
5. Betty
6. Nancy
7. Carol
8. Gloria
Boys’ names potentially due for revival:
1. Donald
2. Richard
3. Kenneth
4. Roger
5. Howard
6. Eugene
7. Carl
8. Raymond
Some of these already show early signs of renewed interest, while others (like Donald) may have too many contemporary associations to make a comeback just yet. But it will be fascinating to see which of these names start appearing on playground rosters in the next decade.
Why This Matters for Parents Choosing Names Today
Understanding the 100 Year Rule can be helpful for parents navigating the tricky process of naming a child. If you’re drawn to vintage names, you’re likely riding the wave of this natural cycle – and that’s perfectly fine! These names feel fresh precisely because they’ve been away long enough to shed their “old person” associations.
On the other hand, if you want a name that will feel distinctive for your child, you might want to consider where names fall in this cycle. Names currently at their peak may feel dated by the time your child reaches adulthood, while names just beginning their comeback might feel more timeless.
Of course, the most important thing is choosing a name you love – regardless of trends or cycles. But understanding these patterns can help you make a more informed choice.
Conclusion: A Useful Theory, Not a Hard Rule
After looking at the evidence, I think the 100 Year Rule captures something real about how name popularity ebbs and flows across generations. There is definitely a pattern where names often return to fashion after skipping roughly 3-4 generations.
However, it’s not a precise science. Cultural shifts, celebrity influences, changing naming practices, and countless other factors affect which names come back and when. The cycle isn’t exactly 100 years, and not all names follow this pattern.
Perhaps it’s better to think of it as the “Grandparent Avoidance, Great-Grandparent Attraction” theory – we tend to avoid our parents’ names but might be drawn to our grandparents’ and especially our great-grandparents’ names.
What do you think? Have you noticed this pattern in your own family names? Are you considering a “100-year-old” name for your child? The beautiful thing about names is that they connect us across generations while still allowing each new generation to put their own stamp on tradition.
