Yay! I'm so glad you don't have to change it. From the description I've read and the associations you have, I do think that the name fits even more now. :)

(And I agree that changing a character's name can be really hard on you. That's why I usually make sure I feel that the name is what the character's essence is - I once named a character Aaron and though that is really unusual here in Germany and very old-fashioned - and though the story is not finished, in my opinion - I'm still incredibly happy with the name. So: go you!)
