Classic, elegant, unusual names that aren't "try hard"

[CannyFradock]

I know I'm pretty much asking for the holy grail of names here, but I'm totally at my wit's end. I just want something y'know...nice for either gender that isn't uber common or attached to a million connotations. I'd quite like a literary, historical or European-sounding name if possible. Any ideas?

Historical European:
Matilda
Joanna
Eleanor
Anastasia
Katherine
Isabella
Alexandra
Florence
Margaret
Ferdinand
Charles
Nicholas
Francis

Literary European:
Eliette
Susanne
Cara
Anton
Henrik
Conrad

George or Georgina.

Elizabeth, Philip, Charles, Mary, Isabella, James, Alexander, Victoria, Louis, Sophie, Alexandra, Maria.

Anna
Simon (much underused these days)
Stephen (likewise, don't know any under 20)
Linus
Patricia
Phoebe
Penelope

Oh, and David. There's some really nice 'classic' but hardly used names, everyone I know with them is older, but not really old IYKWIM.

Henry and Phillip, and Peter

Phillipa, Susannah, Helena

Xanthe

Clemency

Leonora

Frances, and last of all, the always beautiful Mary

We have a Zoe because I think it fits exactly that criteria.

Graham
Edmund
Edward
Miriam
Heather
Hilary

Esme, Ingrid, Sophia, Audrey, Constance, Lyra, Magdalena, Celeste, Eloise, Helena, Melora, Rosa

Aidan, Alexander, Grey, Elliot, Daniel, Henry, Hector, Lachlan, Oscar, Niall, Tobias, Sebastian

Marianne

Gabriel

In which universe are Edward, Daniel, Alexander, Elizabeth and Isabella 'unusual'?

Dashiell
Henry
Arabella
Henrietta
Hector
Harrison
Mathilde or Matilda
Carina

Verity
Marissa
Clarice
Felice
Hugo
Romilly

Naomi
Lavinia
Virginia
Anne
Eugenia
Odette
Simone

Anna
May
Ria
Elizabeth
Oliver
Alexander
Henry
All way too sensible for me but I like them!

Well I don't know any baby Edwards, or Daniels, or Alexanders, or Elizabeths. So yes, they are unusual, for this area at least.

As for Isabella, every second little girl I meet seems to be called that

Lorna
Lara
Phyllida

Alexandra
Ariadne
Artemis
Catharine ...yes I know it's not unusual, but it's a classic that can never be described at 'common'
Clara
Cosima
Francisca
Hermione
Ingrid
Iris
Isolde
Josephine
Lavinia
Ophelia
Orithyia
