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.

Popular baby names in Ireland, 2017

Ireland’s rankings came out early this year! Typically we don’t see them until the start of June, but this year they were released at the end of February.

Anyway…according to Ireland’s Central Statistics Office (CSO), the most popular baby names in the country in 2017 were Emily and Jack.

Here are Ireland’s top 10 girl names and top 10 boy names of 2017:

Girl Names
1. Emily
2. Emma
3. Amelia
4. Grace

Boy Names

In the girls’ top 10, Chloe replaced Lily.

In the boys’ top 10, Harry replaced Oisin.

Interesting factoid: “While there were 2,981 baby boys named John [the #1 boy name] 50 years ago, taken together the five most popular boys’ names in 2017 accounted for 2,765 baby boys.”

The names that saw the most growth in popularity — just within the top 100, I believe — were:

  • Girl names by…
    • Rank: Aoibhin (+81 spots), Nina (+41 spots), Hazel & Pippa (tie; +21 spots each)
    • Number of babies: Aoibhin (+57), Evie (+54), Sadie (+34)
  • Boy names by…
    • Rank: Theo (+33 spots), Jackson (+29 spots), Ruairi (+27 spots)
    • Number of babies: Luke (+45), Logan (+44), Harry (+36)

In 2016, the top two names were Emily and James.
