Children's names, what do you think?

I am a twin myself and the only thing that I worry about with the names that you chose is that Aurora sounds a bit more elegant (and princess-like) than Hadley. I'm not saying you should give them both boring names or anything, but you don't want them to have such different names that one could feel a bit less special than the other. My sister and I are named Nicolette and Hayley, and I've always hated that she had a longer an more exotic name (I'm Hayley). Just something to consider :)
