I love
Amelia, and it sounds okay with
Alexander, but I think
Amelia and
Lilia sound too close, almost rhyming, with a lot of similar sounds. How about
Amelie? Otherwise, middle name suggestions:
Amelia CharlotteAmelia CecilyAmelia GenevieveAmelia CatherineAmelia RoseAmelia GraceAmelia RubyAmelia FlorenceAmelia JaneAmelia VioletAmelia HopeAmelia Madeleine/Madeline
