I like unusual and different and how a name looks written down.

My son is called Bryce, this was unusual when we named him 13 years ago in the UK, the norm way to spell was BRICE but I liked it when written down with the Y, Bryce.

SOOOO....... my preference from your list would be Jazmyn

1) because I like the Y thing as with Bryce
and
2) because, sorry for stating the obvious, Jazz is spelt with a Z and to me that that is how the name sounds when spoken.

sorry for running on a bit, let us know how you go with your spelling dilema.
