We got a sneak preview of the rise of Lainey in the Wyoming rankings a couple of days ago! Lainey has no doubt been influenced by country singer Lainey Wilson.

And the SSA’s press release mentioned that TikToker Kaeli McEwen is likely behind the sudden interest in Kaeli.

If you can explain any of the other rises, please leave a comment!

Update, 3:15pm (MST): I’m working on the debut name posts right now, and just noticed that one of highest-debuting girl names last year was the Eluney-like Aluney (with 21 baby girls).

And what about the names at the other end of the spectrum? Here’s a selection of the baby names that were bestowed just once in Scotland last year:

Unique girl namesUnique boy names
Angharad, Babel, Camellia, Doileag, Ellerby, Fenn, Griva, Hubavena, Iris-Davinia, Jafina, Kinvara, Linamandla, Mhuilinn, Neven, Orlie, Pollaidh, Quinza, Rhumer, Senga, Tweedie, Uxia, Vhairi, Welwitschia, Xiwei, Yolandra, ZarminaAonghas, Brandonlee, Caoimhin-Caolan, Dubhlainn, Excellent, Fragkiskos, Gibby, Howl, Ivaylo, Jophil, Kenai, Lavish, Malverde, Oakes, Padruig, Quinlann, Riordan, Seocaidh, Talorcan, Ultan, Venkata, Wullie, Xabier, Yuan, Zuriel

Possible explanations/associations for several of the above:

  • Pollaidh comes from the name of the Scottish mountain Stac Pollaidh (pronounced “stack polly”). The Scottish name is based on the Norse name for the mountain, Stakkr Pollå, which means “the pinnacle of the pool river.”
  • Senga could be Agnes backwards…or it could be based on the Scottish word seang, meaning “slender.” (Here’s a post about Scotland’s Senga syndrome.)
  • Talorcan is a Pictish name that belonged to several Pictish kings. It’s often spelled Talorgan.
  • Welwitschia (pronounced vel-VIH-chee-uh) is the name of a genus of plants that includes a single species, Welwitschia mirabilis, endemic to the Namib desert in Africa. The genus was named after Austrian physician/botanist Friedrich Welwitsch (1806-1872).

Here’s what Welwitschia mirabilis — often referred to as a “living fossil” — looks like:

(I haven’t been this fascinated by a science-y baby name since Petrichor popped up in Alberta in 2016!)

Finally, here are Scotland’s 2022 rankings, if you’d like to compare last year to the year before.
