According to the Civil Registry of the Isle of Man, the most popular baby names on the island in 2018 were Grace/Gracie and Harry.

The press release didn’t assign rankings to the rest of the top names, so I’ll give them to you in the order in which they were listed…

Girl Names

  • Grace
  • Sophia
  • Amelia
  • Isla
  • Ava
  • Phoebe

Boy Names

  • Harry
  • Alexander

Popular and Unusual Baby Names in Ireland, 2018

According to data from Ireland’s Central Statistics Office (CSO), the most popular baby names in the country in 2018 were again Emily and Jack.

Here are Ireland’s top 10 girl names and top 10 boy names of 2018:

Girl Names

  1. Emily
  2. Grace
  3. Emma
  4. Sophie
  5. Amelia
  6. Ella
  7. Ellie
  8. Mia
  9. Ava
  10. Fiadh (pronounced fee-ah)

Boy Names

  1. Jack
  2. James
  3. Noah
  4. Conor
  5. Daniel
  6. Harry
  7. Luke
  8. Michael
  9. Adam
  10. Charlie

In the girls’ top 10, Ella, Ellie, and Fiadh replace Hannah (now 11th), Lucy (13th), and Chloe (16th). The Irish name Fiadh* comes from the word fia, which means “wild” — in a “wild animal” or “wild deer” sense specifically. (Many sources oversimplify the definition by reducing it to “deer.”)

In the boys’ top 10, Charlie replaces Sean (now both 13th & 74th — see below for an explanation).

New entrants to the girls’ top 100 were Ada, Bella, Bonnie and Ivy. Ada and Ivy were the fastest climbers.

New entrants to the boys’ top 100 were Frankie, Freddie and Theodore. Theodore and Frankie were the fastest climbers.

Something else new to the rankings in 2018? The síneadh fada — an important Irish diacritic that indicates a long vowel. (In Irish, the word síneadh means “stretching” or “prolongation” and the word fada means “long.”) This is what pushed longtime top-five name Sean out of the top 10 entirely in 2018. “Sean” and “Seán” are now being counted as separate names. Currently, Seán ranks 13th while fada-less Sean is way down in 74th place.

Speaking of names with relatively low placement on the list, baby names bestowed just three times each in Ireland last year included…

  • Rare girl names: Aodhla, Erris, Fódla, Rahela, Seoda, Ugne, Xenia
  • Rare boy names: Connla, Iarfhlaith, Liam Óg, Lughaidh, Seánie, Sionnach, Zente

P.S. Here’s the SSA’s table of baby names that increased in rank from 2017 to 2018. The top boy names on their list are Genesis, Saint, and Baker.

More Top Baby Name Drops

A couple of weeks a go we checked out the list of top raw-number rises in the U.S. baby name data, so today let’s balance things out with the list of top raw-number drops.

Just remember that the SSA data doesn’t become very accurate until the mid-to-late 20th century, so many of the numbers below don’t reflect reality all that well.

Same format as usual: Girl names on the left, boy names on the right. Numbers represent single-year decreases in usage. From 1880 to 1881, for instance, usage of the girl name Mary dropped by 146 babies and usage of the boy name William dropped by 1,008 babies.

I’ve already written about some of the names above (click the links to see the posts) and will write about others in the future. In the meanwhile, feel free to beat me to it! Comment below with the backstory on the fall of Shirley in the late ’30s, Linda in the early ’50s, etc.
