I can't help but read
Aileen as Eye-leen not Ay-leen...but either way it sounds nice paired with Liha (Which I'm assuming is pronounced the same as
Leah?)
Athanasois is just a mouthful...and Athan just sounds like
Nathan without the N to me.
I prefer
Marissa and
Moriah.
Roseamara...not sure how to pronounce that.
