Popular Baby Names in Northern Ireland, 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

  1. Grace, 176 baby girls
  2. Emily, 146
  3. Isla, 144
  4. Fiadh, 138
  5. Olivia, 133
  6. Sophia, 125
  7. Sophie, 123
  8. Amelia, 115
  9. Lucy, 112
  10. Freya and Ella, 101 each (tie)

Boy Names

  1. James, 190 baby boys
  2. Jack, 175
  3. Noah, 174
  4. Charlie, 169
  5. Oliver, 134
  6. Thomas, 119
  7. Finn, 112 (tie)
  8. Theo, 112 (tie)
  9. Harry, 111 (tie)
  10. Cillian, 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 strong 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, Dhana, Elmamay, Fodla, Ghalia, Harrie, Jonatha, Krystal-Lake, Lorcagh, Madmazell, Nurvi, Ozde, Riabh, Sauleja, Taleen, Vespa, Wanda, ZilvaniaAdvencio, Alfadil, Boss, Cannis, Dualtagh, Elnino, Fhaolain, Gazza, Herkus, Jailandas, Kai-Bob, Liadhnan, Mitko, Nugmanali, Ocean-Gray, Rathlan, Sujoy, Togi, Vivaan, Weller, Zaslan

(I posted even more of Northern Ireland’s unique baby names over on Patreon.)

NISRA didn’t release the 2019 data during 2020, so I never wrote a post with the 2019 rankings. But I did post 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.

Top 1-Syllable Baby Names, 2020

Which single-syllable names were the most popular in 2020?

I scanned the 2020 rankings for one-syllable names and found these:

Girl Names

  1. Grace (ranked 28th overall)
  2. Claire (57th)
  3. Quinn (85th)
  4. Jade (97th)
  5. Rose (113th)
  6. Faith (136th)
  7. Reese (144th)
  8. Maeve (173rd)
  9. Sloane (181st)
  10. June (182nd)

Boy Names

  1. James (ranked 6th overall)
  2. Jack (21st)
  3. John (27th)
  4. Luke (31st)
  5. Brooks (91st)
  6. Kai (93rd)
  7. Jace (97th)
  8. Beau (109th)
  9. Chase (123rd)
  10. Cole (131st)

Please note that I intentionally left out names that could go either way (1-syllable or 2-syllable) depending upon one’s regional accent. I don’t think this made a difference on the girls’ side, but on the boys’ side I omitted a number of gray-area names (Owen, Wyatt, Charles, Ryan, Miles, Ian, Gael, Rowan, and Myles) that ranked higher than Cole.
