Popular baby names in Northern Ireland (UK), 2021

Northern Ireland

According to the Northern Ireland Statistics and Research Agency (NISRA), the most popular baby names in Northern Ireland last year were Grace and Jack.

Here are the Northern Ireland’s top 10 girl names and top 10 boy names of 2021:

Girl Names

  1. Grace, 182 baby girls
  2. Emily, 150
  3. Fiadh, 149
  4. Olivia, 148
  5. Isla, 138
  6. Sophie, 128
  7. Aoife, 122
  8. Ella, 111
  9. Anna, 106
  10. Sophia, 102

Boy Names

  1. Jack, 193 baby boys
  2. Noah, 191
  3. James, 173
  4. Charlie, 155
  5. Oliver, 131
  6. Theo, 119
  7. Leo, 117
  8. Cillian, 116
  9. Finn, 115
  10. Harry, 114

In the girls’ top 10, Aoife and Anna replaced Amelia, Lucy and Freya. (Two replaced three because there was a tie for tenth last year.)

In the boys’ top 10, Leo replaced Thomas.

And on the other side of the spectrum…

Northern Ireland’s downloadable data only goes down to names given to 3 babies, technically, but this batch of data — like the 2020 batch — included two extra alphabetized sets of names at the end. I believe these sets of names were the ones given to 2 babies and 1 baby, respectively. With that theory in mind, here’s a sampling of names from the second set:

Unique Girl NamesUnique Boy Names
Aodhla, Bediha, Caodhla, Darbie, Edera, Farbhlaidh, Gullandama, Harryanna, Izzy, Jersey, Khalessee, Lasairfhiona, Moya-Grace, Nollaig, Otter, Pupa, Qismina, Rozerin, Samhradh, Toireasa, Ugne, Venba, Wanda, Xanthe, Yarra, ZarkaAstraeus, Brogain, Chulainn, Dubhlainn, Edico, Finnian, Gerard-Og, Holiness, Iollan, Jefaldo, Kestrel, Laochrainn, Murdo, Nivonio, Orin, Padraic, Quevin, Riocht, Struan, Tuathal, Uisce, Vinny, Wai, Xayah, Yeats, Zeyue

Explanations/associations for some of the above…

  • Farbhlaidh – Irish for “overlord, ruler.”
  • Lasairfhiona – Irish for “flame of wine” — lasair meaning “flame,” fhíona meaning “of wine.” (The Irish word for “wine” is fíon.)
  • Nollaig – Irish for “Christmas.”
  • Samhradh – Irish for “summer.”
  • Chulainn – a reference to Cú Chulainn of Irish mythology.
  • Riocht – Irish for “kingdom.”
  • Tuathal – both a legendary conqueror of Ireland (Túathal Techtmar) and the Irish word for “counterclockwise.”
  • Uisce – Irish for “water.” (Also the word upon which “whiskey” was based!)
  • Yeats – a reference to W. B. Yeats, the Irish poet.

Finally, here are the 2020 rankings for Northern Ireland, if you’d like to compare.

Popular baby names in Ireland, 2021

ireland

According to data from Ireland’s Central Statistics Office (CSO), the most popular baby names in the country last year were Fiadh and Jack.

Here are Ireland’s top 10 girl names and top 10 boy names of 2021:

Girl Names

  1. Fiadh, 424 baby girls
  2. Grace, 412
  3. Emily, 388
  4. Sophie, 336
  5. Éabha, 288
  6. Lucy, 287
  7. Mia, 279
  8. Ava, 272
  9. Lily, 271
  10. Ella, 268

Boy Names

  1. Jack, 667 baby boys
  2. Noah, 475
  3. James, 442
  4. Conor, 360
  5. Rían, 357
  6. Liam, 353
  7. Charlie, 345
  8. Daniel, 325
  9. Cillian, 322
  10. Tadhg, 318

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 Northern Ireland (UK), 2020

According to the Northern Ireland Statistics and Research Agency (NISRA), the most popular baby names in Northern Ireland last year were Grace and James.

Here are the Northern Ireland’s top 10 girl names and top 10 boy names of 2020:

Girl Names

  2. Emily, 146
  3. Isla, 144

  6. Sophia, 125

  7. Finn, 112 (tie)
  8. Theo, 112 (tie)
  9. Harry, 111 (tie)

In the girls’ top 10, Fiadh, Lucy and Freya replaced Anna and Evie.

In the boys’ top 10, Finn, Theo, and Cillian replaced Jacob, Daniel, and Alfie.

Now, Northern Ireland doesn’t technically release data on all baby names…but their downloadable tables do include two extra alphabetized sets of names below those that were given to 3 babies. My hunch is that these were the names given to 2 babies and 1 baby, respectively, and that the numbers/rankings were simply stripped out.

So, going with that theory, here are some of the names from the second alphabetized set (the names that I’m assuming were used just once in Northern Ireland last year):

Unique Girl NamesUnique Boy Names
Annagold, Butjilo, Castalia, Cobhlaith, Dhana, Elmamay, Fodla, Ghalia, Jonatha, Krystal-Lake, Lorcagh, Madmazell, Nurvi, Ozde, Riabh, Saorfhlaith, Sauleja, Taleen, Totka, Vespa, Wanda, ZilvaniaAdvencio, Alfadil, Boss, Cannis, Cumhai, Dualtagh, Eimantas, Elnino, Fhaolain, Gazza, Herkus, Jailandas, Liadhnan, Mitko, Nugmanali, Ocean-Gray, Rathlan, Saichairi, Sujoy, Togi, Vivaan, Weller, Zaslan

NISRA didn’t release the 2019 data during 2020, so I never wrote a post with the 2019 rankings. But I did write about the 2018 rankings, which were topped by Grace and James/Noah.

Next door in the Republic of Ireland, the top names of 2020 were Grace and Jack.

The NRS press release mentioned that the popular British crime drama Peaky Blinders has given a boost to the baby names Cillian, Polly and Chester. (Polly and Chester are characters in the show; Cillian refers to star Cillian Murphy.) It also noted that Ezra has become more popular thanks to English singer/songwriter George Ezra.

Of the nearly 50,000 babies born in Scotland last year, more than 5,000 — over 10% — were given a one-of-a-kind first name. Here are some of the names bestowed just once in Scotland in 2019:
