Help me with girl name

So,I’m writing a book series and the problem is that I’ve alredy wrote the first one,but havent choose names for caracters.In my book I just call them by random letters like:S,K,Z etc.I’ll be extremely glad if you’ll help me.

Main heroes:
K-the young lady(in book her age will differ from 16 to 30),she’s the main characeter.inspired by [name_u]Madison[/name_u] [name_m]Montgomery[/name_m] from AHS and [name_f]Lilian[/name_f] from Remark’s book.She’s an incredebly talented ballerina girl,like a wonderkind(dont know how to write this in eng) from rich and aristocratic upper class family.She is Russian and studied in Vaganova’s Academy.
Appearance: big blue-grey deep and sad bambi eyes like “eyes of lost child”,hair of “rusyi” color (its referred as light brown in english) and shes very graceful.She looks innocent,fragile and naive,like [name_f]Daisy[/name_f] from Great [name_m]Gatsby[/name_m].
So,I need a name that has something russian in it,but also romantic and unusual.
The book genre is drama,so there will be death and tragedies.

I’m gonna suggest [name_u]Sasha[/name_u] or [name_f]Svetlana[/name_f] Kournikova.

[name_f]Varya[/name_f] is my favorite Russian-esque name. It feels soft and snowy to me. Very smooth and graceful.

[name_f]Zhanna[/name_f] is also pretty, though more spunky.
