Hello,
We are thinking of calling our daughter Alexandra Aurora. Our last name starts with a J. I like the fact that the two names together mean defender of dawn, just hope it won't mean she's an early riser 
I am aware that she will be A.A. and that for some it will be associated with alcoholics anonymous, but we've been through so many options and this is the one we like the best as it also works in both our mother-tongues (English and Dutch).
Would love to hear your thoughts on this combination.
