I actually prefer Europe, I was thinking the British Isles but Scandinavia is interesting too. Of course, if you have other suggestions, I'm more than willing to listen!
Louisa would like at least two children, as she can't picture her lfie without her sister and figures no child of hers should have to. She hasn't settled on a maximum number of kids, so starting at 4 like Edward would like is perfect ;)
As for surnames, I really like Black. I think it's one of the coolest surnames there is, haha.
How long have Edward and Louisa been married for now? Oh, and I just realised I hadn't given Louisa a middle name, so she is now Louisa Margaret.
