Middle names for a girl?? Help!

Well.. we have names picked out already, (actually already had them picked out for awhile), but I can't think of a good middle name for a girl. The name I have picked out for this baby is Magdalena, (my mother in law's middle name & I think it is a beautiful classic.. plus we like the nickname Lena for short). The middle names I've come up with so far are Nicole and Ava but I'm not too sure if they flow. Any ideas ladies?? I like unique names but not "weird" kind of unique. And I really like classics. ?
