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.

And here’s a sampling of the many names that were bestowed just once in Sonoma last year:

Unique girl namesUnique boy names
Ameyalli, Beliana, Colette, Delphie, Ellora, Fiadh, Gwendolyn, Honorae, Ilisapeci, Jessune, Khilana, Lucibell, Merari, Norma, Oriah, Pixel, Riyana, Soluna, Teteoinnan, Ume, Velexia, Wrenlee, Xochitl, Yetzi, ZantedechiaAriodante, Bruce, Canaan, Dovydas, Endrick, Favian, Gedaliah, Hewitt, Itztli, Jessiah, Kidder, Ledson, Miro, Nash, Orbelin, Paz, Rapha, Sigaserau, Tovius, Uniquo, Ventura, Wicahpi, Xolotl, Yoali, Zianni

Some possible explanations/influences for a few of the above:

  • Ameyalli means “spring, fountain” in Nahuatl.
  • Ariodante is the name of an opera (first performed in 1735) by George Frideric Handel.
  • Itztli refers to an “obsidian blade” in Nahuatl.
  • Teteoinnan is the name of a Nahua deity. (The name means “mother of the gods” in Nahuatl.)
  • Wicahpi means “star” in Lakota.
  • Xolotl refers to the “divine force of lightning and death” (among other things) in Nahuatl.
  • Zantedechia is one letter away from Zantedeschia, the name of a genus of flowering plants. (The calla lily is a member of this genus.) The genus was named after Italian physician/botanist Giovanni Zantedeschi (1773-1846).

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