For some reason Sophira comes to mind!

I picked Savannah - lovely name! I actually dont think the others go with your surname anyway
If you use Savannah I think it needs a one syllable middle name like Joy or Lea
I adore Sophira (not to mention its the dragons name in Eragon) but again DH doesn't like it and I agree completely about the middle name funnily Lea was one I had thought of but haven't mentioned.
