Rare girl namesRare boy names
Alfia, Bluebella, Buddug, Coni, Dolcy, Ephelia, Fen, Glesni, Harasees, Indica, Jodh, Khulood, Larnie, Myrto, Nectaria, Omuwa, Pip, Qiraat, Reevie, Sorrel, Tegwen, Udaina, Vani, Waverly, Xanthea, Yvaine, ZoellaApollon, Banksy, Blaidd, Catalin, Dishan, Eifion, Fayzan, Gurvir, Haaland, Iverson, Jibriel, Kirtan, Lucho, Monaco, Nalan, Orwell, Prevail, Qusay, Ranbir, Sebbie, Tassilo, Ulrich, Vedh, Wildan, Xavian, Yamac, Zuko

Possible explanations/associations for several of the above:

  • Blaidd means “wolf” in Welsh. (It’s also the name of a half-wolf character in the 2022 video game Elden Ring.)
  • Buddug is based on the Welsh word budd, which means “benefit, profit.” It’s the Welsh equivalent of Boudicca (the name of the ancient British queen who led a revolt against the Romans).
  • Fen might refer to the type of wetland.
  • Glesni means “blueness” or “greenness” in Welsh.
  • Haaland is the surname of Norwegian soccer player Erling Haaland (who currently plays for Manchester City F.C.).

Here are the 2023 rankings for Scotland and Northern Ireland — the other two countries in the United Kingdom — and the 2022 rankings for England and Wales, if you’d like to compare last year to the year before.
