I only glanced at the others, so I apologize if I repeat any. I definitely for the most out-there, guilty pleasure names that I love. Hopefully this is what you meant!
Wilhelmina - A couple of years ago I would have scoffed at this "clunky" name, but now I love how substantial it is with its soft, lilting syllables and endless nickname potential. It has a meaning that is strong for a female name, which appeals to me. Willa is an adorable nn choice.
Eulalia- I'd never have the guts to use it, but all those symphonic syllables! It's so musical to me.
Ancasta - Celtic goddess
Seneca - At first, this was a boys-only name for me, and then someone brought up the Seneca Falls Convention, and I realized what a great feminist name it would be. Now it's a unisex name in my mind. (And I usually hate unisex names.)
Clementine - Doesn't seem rare, but it's actually been out of the top 1000 for decades! I love it, it's on my short list
There are more, but I gotta go. I'll maybe add more tomorrow :) Hope this helps!
Dagny is our top name right now. Evander is our son's name, only 80 were born in the US in 2012. My husband's favorite name is Elliava. I know an Eagle Scout Severin (SEV-rin) whose name I love. My bestie's little girl is Vayla.
That is all I can think of right now.
One of my fav names that I can't personally use is Wilder.
Khotso (pn Hote-soh, means peace in Sotho)
Callista/Callisto (I like it with the o ending)
That's all I can think of for now... Seems I'm on a ancient Greek kick tonight...
I don't have a lot of rare boy names because I like really common boys names but here we go
Aurelien, Alaric, and Theseus
For little girls I love the names Maple Menorah and Easter Galilee.
Other ideas are:
Aira - A Finnish girls name meaning 'messenger'. It's pronounced 'eye-ra' and you can hear it on Forvo.
Jory - Boys name. The Cornish form of George.
Thank you all so much! Sometimes it feels like I've seen every name on here but so many of these suggestions are great. Clementine is one of my favorites but I feels so much more popular than it is. Does exposure like that take away from some of the novelty for you when looking for an uncommon name? Balthazar is also a favorite but I wonder if it sounds too heavy on a kid.
We're going with Linus. It's not in the top 1000 (and hasn't been in almost a century). Rich history: son of Apollo, 2nd pope after Peter, inventors of Yale-brand locks, 2-time Nobel prize winning chemist, and acclaimed computer programmer.
My top for a girl right now is Fiala. It's a Czech name meaning violet and I think it's lovely.
