If Leon and Léon had been counted as a single name, their combined total (585) would have been enough to edge Arthur (584) out of second place on the boys’ list.

And the gender-neutral name Lou managed to pop up on both lists in nearly the same spot: 26th for girls, 27th for boys.

(I’m a little surprised that as many as 5 baby girls in Belgium got the English word “believe” as their first name. I wonder if something specific was influencing that usage…?)

This time around, Belgium also highlighted the girl and boy names that saw the largest increases and decreases in usage over the last decade (2011-2021). The top 5 in each category were…

  • Girl names
    • Largest increases: Alba, Ellie, Ellis, Alya, Cilou
    • Largest decreases: Lisa, Laura, Julie, Lotte, Anaïs
  • Boy names
    • Largest increases: Georges, Lio, Gaston, Otis, Lyam
    • Largest decreases: Maxime, Thomas, Simon, Wout, Nathan

Finally, since this is the first time I’m posting rankings for Liechtenstein, let’s throw in the country’s top baby names for the two previous years:

  • In 2019: Emma (9) and a four-way tie between Fabio, Leon, Matteo and Paul (4 each).
  • In 2018: Valentina (7) and a three-way tie between Ben, Leon, and Samuel (4 each).

In the girls’ top 10, Éabha and Lily replaced Amelia and Hannah. (In both 2019 and 2020, Éabha was the fastest-rising girl name in Ireland.)

In the boys’ top 10, Rían, Cillian, and Tadhg replaced Finn, Fionn, and Harry.

Newbies to the girls’ top 100 were Indie, Ayla and Lottie; newbies to the boys’ top 100 were Teddy, Daithí, Páidí, Jaxon, Brody, Ted, Hunter, Tadgh, Tiernan, and Arlo.

The fastest-rising names in the top 100 in terms of numbers of babies were:

  • Croía (+60 baby girls), Emily (+59), Fiadh (+58), Éabha (+54), Isla (+52)
  • Rían (+72 baby boys), Jack (+70), Danny (+57), Theo (+53), Ollie (+51)

The fastest-rising names in terms of rank were:

  • Croía (+43 spots), Indie (+28), Ayla (+28), Fíadh (+24), Daisy (+21)
  • Ted (+49 spots), Hunter (+38), Hugo (+35), Brody (+35), Teddy (+31)

Rían (which was already on the rise) and Croía have both given a boost recently by Irish MMA fighter Conor McGregor, who welcomed a daughter named Croía Mairéad at the start of 2019 and a son named Rían in May of 2021.

Here’s what writer and Irish language activist Darach Ó Séaghdha’s had to say about the rise of Rían (and Éabha):

Given that the first name Ryan started to decline in popularity in the 2010s around the time Rian and Rían began to ascend it is reasonable to see Rían as an update or replacement to Ryan, much as Éabha has climbed in popularity as Eve, Ava and Aoibhe have wavered.

He also noted that “Rían and Rian would be the [most popular] Gaeilge-origin boy name if counted together, edging ahead of Conor.”

P.S. To follow up on Friday’s post about the free lighthouse tour…the name Patrick is currently ranked 19th in Ireland, but none of the other three names (Paddy, Pat, or Patricia) rank anywhere near the top 100. That said, one of the names new to the boys’ top 100 last year was Páidí (pronounced paw-dee) — a pet form of Pádraig, which is an Irish form of Patrick.
