Ana Allegra is an interesting name. I had a friend in highschool called
Allegra, and now I don't even associate it with the medicine (an allergy medicine in the U.S.) until someone reminds me. I've always thought it sounded very much like it's meaning, light and joyful.
Ana is a classic and nice, too.
My favorite of your combos are:
Ana Josephine and
Allegra Naomi
