Just that really. We have an Elizabeth and our second daughter is due in September. I love the name Raphaela for the next one but people have mentioned that they won't 'go' together. To be honest, we've only ever called DD1 Betty and we'd probably shorten DD2 to Raphy (which I think go together) but I wonder if other people have non-matching names, if it's an issue, if you couldn't care less etc.?
