I've got a fine
Savannah niece, but I really dislike it as a human name.
Hannah is slightly better than
Anna, but they're both dull. And as a combo, I cannot see the point of creating confusion and, yes, amusement just because of liking the names.
Savannah Lane sounds like an address, which doesn't help.
Ann-Louise is a bright merger with a cool Scandinavian feel. Perhaps she could consider it? And
Lane Savannah would be a huge improvement on
Savannah Lane! But, right now, I'm hoping for at least one boy.
