I think
Emily is a sweet name, and it isn't popular at all here (the Catalan form Emília is totally out dated), so this isn't an issue for me, but even without knowing a single one, I think of it as a plain name (too much BtN, that's it!) .
And about the combos...Iris
Emily would be much better, imo, and
Emily Sarah is nice, but a bit boring, I think.
