Five-Name Friday: Boy Name for Genevieve’s Brother

five name friday, boy name

You’re at a food truck, waiting for a shawarma sandwich. Waiting beside you is a friendly woman who happens to be pregnant. The two of you chat for a few minutes and, as you’re both handed your respective sandwiches, she mentions that she still can’t think of a name for the baby. Then she tells you the gist of what she’s looking for:

I’m looking for a name for the brother of Genevieve. Would like to downplay the Francophile and have nickname (traditional or unique) potential.

“Do you have any suggestions?”

You’re a name-lover, and you could potentially give her dozens of suggestions on the spot. But you’ve got to get going, so you only have time to give her five baby name suggestions before the two of you part ways.

But here’s the fun part: Instead of blurting out the first five names you come up with (which is what you’d be forced to do in real life) you get to press a magical “pause” button, brainstorm for a bit, and then “unpause” the scenario to offer her the best five names you can think of.

Here are a few things to keep in mind as you brainstorm:

  • Be independent. Decide on your five names before looking at anyone else’s five names.
  • Be sincere. Would you honestly suggest these particular baby names out loud to a stranger in public?
  • Five names only! All names beyond the first five in your comment will be either deleted or replaced with nonsense words.
    • EXCEPTION ALERT: This time around, because the request is wide-open and specifically mentions unique nicknames, you may include (if you want) up to two unexpected nicknames. For instance, I’ll allow “Theodore (Dorie),” but not “Theodore (Theo).”

Finally, here’s the request again:

I’m looking for a name for the brother of Genevieve. Would like to downplay the Francophile and have nickname (traditional or unique) potential.

Which five baby names are you going to suggest?

Popular Baby Names in Denmark, 2015

According to data from Statistics Denmark, the most popular baby names in the country in 2015 were Sofia and William.

Here are Denmark’s top 10 girl names and top 10 boy names of 2015:

Girl Names Boy Names
1. Sofia, 555 baby girls
2. Freja, 459
3. Ella, 449
4. Alma, 445
5. Anna, 419
6. Emma, 415
7. Laura, 412
8. Clara, 398
9. Ida, 390

6. Oscar, 480
7. Victor, 478
8. Malthe, 455
9. Alfred, 425
10. Carl, 418

Emma, the former #1 girl name, dropped to 6th place last year. Alma, on the other hand, jumped from 11th to 4th and replaced Karla in the top 10.

On the boys’ side, Alfred (jumping from 17th to 9th) and Carl replaced Frederik and Magnus.

In the top 50, the girl names Gry, Naya, and Silje replaced Alba, Naja, and Malou, and the boy names Jakob, Lauge, Milas, Silas, Theo, Thor, and Viggo replaced Andreas, Bertram, Daniel, Jacob, Jonas, Nikolaj, and Sander.

(Gry means “dawn” in Danish and Norwegian, Silje is a diminutive of Cecilia, and Lauge is based on the Old Norse byname Félagi, meaning “fellow, partner, mate.”)

Here are Denmark’s 2014 rankings.

Olivia Twenty, Named for $20

Children’s book author Roald Dahl, who was named after Roald Amundsen and who also created the Fifinella gremlin, was born in Wales in 1916.

He married American actress Patricia Neal in 1953 and they had a total of five children together.

Their first baby was named Olivia Twenty. Why?

Olivia Twenty was born in New York on April 20, 1955, and named after her mother’s favorite Shakespearean heroine, the date of her birth, and the fact that Roald had $20 in his pocket when he came to visit Pat in the hospital.

And their second child, originally called Chantal Sophia, ended up getting a name change:

A few days after Chantal had been christened, Roald realized her name rhymed with Dahl and renamed her Tessa.

The last three three Dahl children were named Theo Matthew, Ophelia Magdalena, and Lucy Neal. My guess is that Ophelia is another Shakespeare reference, and that Sophia and Magdalena came from Dahl’s mother, Sofie Magdalene. I’m not sure what inspired the other names.

[Sadly, Olivia Twenty died of the measles in 1962, before a reliable measles vaccine had been developed.]

Popular Baby Names in Luxembourg, 2015

According to the Luxemburger Wort newspaper, the most popular baby names in Luxembourg in 2015 were Emma and Matteo.

Here are Luxembourg’s top 5 girl names and top 5 boy names (maybe) of 2015:

Girl Names Boy Names
1. Emma
2. Julia
3. Marie
4. Lia
5. Charlotte
1. Matteo
2. (Theo?)
3. (Leo?)
4. (Louis?)
5. (Noah?)

I’m not sure about the boy names — the order was wasn’t explicitly stated. Here’s the quote:

For boys, the most commonly given name was Matteo. It seems that names ending in -eo were all the rage as Theo and Leo also experiencd [sic] considerable popularity.

Louis and Noah, the names of Grand Duke Henri’s two grandsons, continued to be popular among Luxembourg parents.

My source article also mentioned that “Portuguese, Chinese, Scandinavian and Irish-sounding names made a mark in Luxembourg with Jimao, Jia, Côme and Aidan making it into registers.”

In 2014, the top baby names in Luxembourg were Emma and Gabriel.

Popular Baby Names in Belgium, 2014

According to data from Statistics Belgium, the country’s most popular baby names in 2014 were Emma and Louis.

Here are Belgium’s top 10 baby names:

Girl Names Boy Names
1. Emma, 653 baby girls
2. Louise, 584
3. Elise, 480
4. Olivia, 459
5. Lina, 383
6. Marie, 376
7. Lucie, 359
8. Ella, 348
9. Alice, 347 (tie)
10. Juliette, 347 (tie)
1. Louis, 622 baby boys
2. Lucas, 619
3. Arthur, 610
4. Adam, 575
5. Noah, 562
6. Liam, 513
7. Mohamed, 468
8. Nathan, 455
9. Jules, 442
10. Mathis, 428

In the girls’ top 10, Ella and Alice replace Léa and Mila. The boys’ top 10 includes the same 10 names.

But there’s more! Like Switzerland, Belgium breaks name data down by region. So let’s also check out the top names within each region.

About 58% of Belgians live in the northern region, Flanders, where the official language is Dutch. Here are the top 10 baby names in Flanders:

Girl Names Boy Names
1. Emma, 381 baby girls
2. Elise, 351
3. Louise, 344
4. Ella, 329
5. Marie, 309
6. Noor, 269
7. Lena, 251
8. Julie, 246
9. Lotte, 231
10. Mila, 227
1. Lucas, 329 baby boys
2. Liam, 316
3. Vince, 309
4. Arthur, 307
5. Noah, 300
6. Finn, 298
7. Mathis, 276
8. Louis, 274
9. Seppe, 248
10. Jules, 244 (tie)
10. Stan, 244 (tie)

In the girls’ top 10, Lena replaces Fien (short for Jozefien, the Dutch form of Josephine). In the boys’ top 10, Seppe and Jules replace Lars and Alexander.

I would have guessed that Seppe was a diminutive of Joseph (akin to the German name Sepp). According to a Behind the Name contributor, though, Seppe is a West Frisian name that can be traced back to Sibe, a “Frisian short form of masculine names that have sigu or sigis for a first element” and a second element begins with the letter b (e.g., Sibald, Sibert).

About 32% of Belgians live in the southern region, Wallonia, where the official language is French (and, in some areas, German). Here are the top 10 baby names for Wallonia:

Girl Names Boy Names
1. Léa, 263 baby girls
2. Lucie, 244
3. Chloé, 218
4. Zoé, 216
5. Emma, 208
6. Louise, 200
7. Alice, 200
8. Camille, 198
9. Olivia, 191
10. Jade, 154
1. Hugo, 314 baby boys
2. Louis, 308
3. Gabriel, 255
4. Arthur, 245
5. Nathan, 242
6. Théo, 235
7. Lucas, 225
8. Ethan, 213
9. Noah, 208
10. Tom, 195

In the girls’ top 10, Jade replaces Manon. The boys’ top 10 includes the same 10 names.

About 10% of Belgians live in the Brussels Capital Region, where the official languages are Dutch and French. Here are the top top 10 baby names for Brussels:

Girl Names Boy Names
1. Lina, 119 baby girls
2. Aya, 84
3. Sarah, 78
4. Sofia, 77
5. Nour, 70
6. Yasmine, 67
7. Malak, 66
8. Emma, 64
9. Sara, 62
10. Anna, 56
1. Adam, 233 baby boys
2. Mohamed, 195
3. Rayan, 94
4. Gabriel, 82
5. David, 81
6. Imran, 69
7. Amir, 66
8. Lucas, 65 (tie)
9. Youssef, 65 (tie)
10. Yanis, 59

In the girls’ top 10, Malak and Anna replace Ines and Louise. In the boy’s top 10, Amir, Lucas and Yanis replace Ayoub, Nathan and Anas.

Morocco World News notes that “heavy immigration from Morocco and other Muslim countries has left its traces, as Mohamed has been the most common male name in the Brussels Region recently.” Mohamed was the #1 boy name in Brussels from the late 1990s until 2011, in fact. And the same wave of immigration has given a big boost to many other Arabic names (Amir, Bilal, Hamza, Imran, Malak, Nour, Rayan, Yousra, etc.) within the last few decades.

Cosby Show Baby Names – Vanessa, Keshia, Phylicia…

cosby showRemember The Cosby Show?

The ground-breaking ’80s sitcom focused on the Huxtables, a well-off African-American family living in New York City. It starred Bill Cosby as Heathcliff “Cliff” Huxtable.

The show ran from mid-1984 to mid-1992 and was the top-rated program in the nation for 5 consecutive seasons.

And it influenced a whole bunch of baby names, such as…

Vanessa & Tempestt

Vanessa, the second-youngest Huxtable child, was played by Tempestt Bledsoe. The baby name Vanessa saw its highest-ever levels of usage during the years the show was on:

  • 1989: 6,955 baby girls named Vanessa (ranked 50th)
  • 1988: 7,515 baby girls named Vanessa (ranked 41st)
  • 1987: 7,345 baby girls named Vanessa (ranked 43rd)
  • 1986: 7,367 baby girls named Vanessa (ranked 43rd)
  • 1985: 7,562 baby girls named Vanessa (ranked 42nd)
  • 1984: 7,153 baby girls named Vanessa (ranked 45th)
  • 1983: 6,383 baby girls named Vanessa (ranked 49th)

And the baby name Tempestt debuted on the charts the year after the show premiered:

  • 1990: 70 baby girls named Tempestt
  • 1989: 98 baby girls named Tempestt
  • 1988: 72 baby girls named Tempestt
  • 1987: 87 baby girls named Tempestt
  • 1986: 78 baby girls named Tempestt
  • 1985: 36 baby girls named Tempestt [debut]
  • 1984: unlisted
  • 1983: unlisted

The name Tempest also got a boost during the last half of the ’80s.

Rudy & Keshia

Rudith “Rudy” Huxtable, the baby of the family, was played by Keshia Knight Pulliam. The baby name Keshia entered the top 1,000 for the very first time the year after the show premiered:

  • 1990: 385 baby girls named Keshia (ranked 594th)
  • 1989: 496 baby girls named Keshia (ranked 479th)
  • 1988: 398 baby girls named Keshia (ranked 547th)
  • 1987: 483 baby girls named Keshia (ranked 457th)
  • 1986: 511 baby girls named Keshia (ranked 426th)
  • 1985: 321 baby girls named Keshia (ranked 596th)
  • 1984: 96 baby girls named Keshia
  • 1983: 64 baby girls named Keshia

The name Rudy also rose in usage, and the variant spelling Rudi debuted on the charts in 1985.


Huxtable mother Clair was played by actress Phylicia Rashād. The baby name Phylicia entered the top 1,000 for the first time two years after the show premiered:

  • 1990: 257 baby girls named Phylicia (ranked 787th)
  • 1989: 265 baby girls named Phylicia (ranked 744th)
  • 1988: 286 baby girls named Phylicia (ranked 679th)
  • 1987: 290 baby girls named Phylicia (ranked 649th)
  • 1986: 213 baby girls named Phylicia (ranked 789th)
  • 1985: 122 baby girls named Phylicia
  • 1984: 13 baby girls named Phylicia
  • 1983: 7 baby girls named Phylicia

Theo & Malcolm-Jamal

Theo, the middle Huxtable child (and the only male in the family besides Cliff) was played by Malcolm-Jamal Warner. The baby name Theo almost tripled in usage the year after the show premiered:

  • 1990: 66 baby boys named Theo
  • 1989: 75 baby boys named Theo
  • 1988: 77 baby boys named Theo
  • 1987: 75 baby boys named Theo
  • 1986: 85 baby boys named Theo
  • 1985: 76 baby boys named Theo
  • 1984: 23 baby boys named Theo
  • 1983: 26 baby boys named Theo

Usage of the baby name Malcolm also began to rise in the mid-’80s, and the baby name Malcolm-Jamal (rendered Malcolmjamal by the SSA, which leaves off hyphens) debuted on the baby name charts two years after the show premiered:

  • 1990: unlisted
  • 1989: unlisted
  • 1988: 5 baby boys named Malcolm-Jamal
  • 1987: unlisted
  • 1986: 5 baby boys named Malcolm-Jamal [debut]
  • 1985: unlisted
  • 1984: unlisted
  • 1983: unlisted

(Where did actor Malcolm-Jamal Warner get his name, btw? He was named after civil rights activist Malcolm X and jazz pianist Ahmad Jamal.)

So now here’s the question: Does The Cosby Show beat Family Ties in terms of impact on the baby name charts? Cosby clearly affected a greater number of names, but is that enough to offset the massive rises of both Mallory and Alex?

P.S. Did you know that Sondra, Denise, Theo, Vanessa and Rudy Huxtable were loosely based on Cosby’s real-life kids Erika, Erinn, Ennis, Ensa, Evin?
