It’s a lovely name, I like it a lot.
But of course it’s not classic, that’s quite a strange question. I would be very surprised indeed if you knew anybody your age or older with that name and apart from Harry Potter it’s not a name used in any other films or books as far as I know. Also, given that it is trendy at the moment it is unlikely to be timeless because it will be associated strongly with this time period and will therefore eventually become dated after a while.
