My name is
Georgia, so guess which I prefer?
Pros:
Not common but most people have heard of it.
Has a strong history.
Good nn potential, although most people will not automatically use a nn - most will use
Georgia unless told otherwise.
Cons:
She might get tired of hearing the same songs.
At least in the U.S., fewer people know how to spell it nowadays.
Also fewer people know how to pronounce it. In recent years, I've been hearing jor-JEE-ah more and more.
I honestly do not know how to pronounce
Isla, although I notice it is mentioned frequently here. I gather it is well-liked.
