I really like
Gael. I appreciate that
Gaël clarifies how it should be pronounced it you understand diacritics, but in the US I can understand not using it since so many of us don't know the keyboard shortcuts to type it and aren't familiar with many diacritics.
Gael and
Noelle are too rhyme-y together for my personal taste, but both names have nice sounds and I actually appreciate that at least the spelling isn't too match-y.
