Nadine Audra is beautiful. :)
I agree
Catherine makes it a bit plain, it was just the first middle that popped in my head during the time of writing this post.
I like
Nadine Eliza,
Nadine Nicole*, and
Nadine Angela* too. I briefly thought of
Nadine Nicole at the time of writing this as well, Nicole’s my mother’s name and I think the alliteration sounds nice. Angela’s one of my favorite “old” names and
Nadine Angela has a really pretty, soft sound to it.
