Which name do you like best?

In my book I have a character who is a witch who leaves her coven to help my main character, Noelle, fight against them. I originally named her Devyn, but I've been told it sounds trampy and I DON'T want that. Besides, I don't think it fits her well. She has platinum blonde hair and icy blue eyes with pale skin. She is often found staring off into the distance and is a girl of few words. She is 14 years old.

A few names I have picked out are:

Indira (I love this one, but a character's name is Iris so I can't really use it...)

McKenna

Juliet

Leola/Leona/Enola

Trinity

Lynne

I do not like the name Destiny for this character.

If you have better ones please suggest them! Thank you so much! This will for sure help me!
