I'm definitely voting for
Alyssa, out of the three; it's such a beautiful, graceful name in my opinion. It's a very common name among my generation, but it never seemingly became overused, in my opinion- anyway, she'd (most likely) be the only
Alyssa in her class, nowadays! My favorite combination has to be
Alyssa Gabrielle Odette Perry, since I feel it flows nicer than all the other choices (including
Elsa and
Amelia).
May I suggest
Alyssa Mariana Odette Perry,
Alyssa Tamara Odette Perry,
Alyssa Janine Odette Perry,
Alyssa Roxanne Odette Perry,
Alyssa Hannah Odette Perry,
Alyssa Cora Odette Perry,
Alyssa Rachel Odette Perry, or
Alyssa Ruth Odette Perry?
