Popular baby names in Monaco, 2022


The European micro-state of Monaco lies on the French Riviera. Though it shares a border with only France, it’s just a few miles away from France’s border with Italy.

Last year, Monaco welcomed 862 babies — 427 baby girls and 435 baby boys.

What were the most popular names among these babies? Emma and Leonardo.

Here are Monaco’s top 5 girl names and top 5 boy names of 2022:

  4. Chloé
  5. Stella

Boy Names

(Leonardo has also been the #1 boy name in Italy lately.)

What other names have topped the rankings within the last few years? Here are Monaco’s most popular baby names of 2021, 2020, and 2019:


In 2021, a total of 976 babies (478 girls and 498 boys) were born in Monaco.

My source for the 2019 rankings suggested that Charlotte was the #1 girl name because of Charlotte Casiraghi — the daughter of Monaco’s Princess Caroline, who is in turn the daughter of Grace Kelly. Charlotte was making headlines in mid-2019: She married film producer Dimitri Rassam civilly in Monaco in early June, then religiously in France later the same month.

Last year, the most popular baby names in the Brazilian city of Toledo (located in the southern state of Paraná) were Alice and Miguel.

According to local newspaper Gazeta de Toledo — which published a single, provisional set of rankings for Toledo in late December — these were the city’s top 50 baby names overall in 2022:

  1. Miguel, 32 babies
  2. Alice, 29 – pronounced ah-lee-see in Brazilian Portuguese.

  46. Guilherme, 6
  47. Rebeca, 6
  48. Eloah, 6
  49. Antonella, 6
  50. Felipe, 6

The newspaper mentioned that Maria Alice has been on the rise in Brazil since the mid-2020 birth of celebrity baby Maria Alice, firstborn daughter of Brazilian singer Zé Felipe and Brazilian influencer Virginia Fonseca. (The couple’s second daughter, Maria Flor, was born in late 2022 — making “Maria Flor” a combo to look out for in future Brazilian rankings.)

The name Rebeca also rose in 2022 following the success of Brazilian gymnast Rebeca Andrade at the 2020 Summer Olympics, which were held in mid-2021 due to COVID-19. Andrade won a gold medal in the vault and a silver medal in the individual all-around (placing second to Sunisa Lee of Team USA).

I’ve never posted rankings for Toledo before, but I did post Brazil’s 2021 rankings a few months back, if you’d like to compare this list to that one.

Some thoughts on a few of the above…

  • Künkyi and Tenzin are Tibetan.
  • Nevia and Nevio are Italian. They derive from the Roman family name Naevius, which was based on the Latin word naevus, meaning “birthmark” or “mole (on the body).”
  • Rron is an Albanian. It was created from the word rronj, a dialectal form of rroj, which means “to live, to survive.”

The Subban siblings

The Subban brothers Jordan, Malcolm, and P. K. (at the 2013 NHL Draft)
Jordan, Malcolm, and P. K. Subban

I’ve only recently started watching hockey, so the first time I heard about Canadian player P. K. Subban was when he announced his retirement a few months ago.

He’s not the only player I know of who goes by his initials. One of the Colorado Avalanche players is called J. T. Compher, for instance. But I’d say P. K. has the most intriguing set of initials. (In contrast, the combo “J.T.” is so common that some parents simply register “JT” as a legal name.)

So, what do Subban’s initials stand for?

Here’s the answer, courtesy of Sports Illustrated:

P.K. stands for Pernell Karl. When he was born, his mother, Maria, thumbing through a movie magazine in her hospital bed, spotted a story about actor Pernell Roberts. The name clicked. Pernell for Adam Cartwright from Bonanza. Karl for his father.

When he was drafted by the Montreal Canadiens in 2007, P. K. was asked what his initials stood for, and he cheekily replied: “Penalty-killer.” (In fact, you do hear hockey announcers say “PK” — an acronym for “penalty kill” — during televised games sometimes.)

P. K. Subban has four siblings: two older sisters and two younger brothers. Both brothers are also professional hockey players with hyphenated names:

  1. Nastassia (pronounced nah-STAH-zee-ah)
  2. Natasha
  3. Pernell-Karl, or “P. K.”
  4. Malcolm-Jamaal, or “Malcolm” (drafted in 2012 by the Boston Bruins)
  5. Jordan-Carmichael, or “Jordan” (drafted in 2013 by the Vancouver Canucks)

I have to imagine that Malcolm’s name was somehow inspired by actor Malcolm-Jamal Warner, who played Theo on The Cosby Show, though I haven’t found any proof of this yet.

What are your thoughts on these names? And, have you spotted any interesting sets of initials recently?
