Love all these names but I'm concerned that they won't sound good with our surname. It begins with S and rhymes with button?
Also, I think that Elsa is considered to be a shortened version of Elisabeth but we'd want to use Elizabeth. What do you think?
Another fly in the ointment is that our DS is called Isaac and I think Isaac and Iris will sound too matchy (and I think there's a book about polar bears called 'Iris and Isaac').
With all these doubts I know I should just forget them all but I just think they're all so lovely.
