I've never been able to figure out where this name came from, if it's even legal or just a very modern name, like
Nevaeh. I can't deny that I love it, though. I would also pronounce it a-QUINN-a. It also reminds me of
Thomas von Aquin, the philosopher and theologist, and I love his surname.
To me,
Kaia Aquinnah is a bit too hard, it doesn't really flow...
Kira Aquinnah isn't much better, either, though...
