Man is
Aureliana hard for me to say.
The way I pronounce them is closer to "Aw" like
August and
Audrey, not "Ow" like Cow. However I'm imagining these with American accents different from my own and I feel the "Aw" is more of a softer "Or", even with
August and
Audrey.
Autumn, for example, sounds closer to "our-tom" than "aw-tum" so
Aurelia is more like "our-ree-lee-ah"
Also the "aw-rail-ya" suggestion with the "Aw" and the "Ay" sounds bloody awful. The "Eh" suggestion isn't much better honestly
So long as its "our-ree-lee-ah" I love
Aurelia.
Aureliana ... not so much. Can't bleeding say it for a start xD
