I like it. I love Nyssa. I'm not a fan of Cherise on it's own but I think it goes well as a middle name for Nyssa.
that's how I feel about Cherise, not a huge fan of it by it self but I think it goes well with Nyssa :-) I went through whole list of names and Cherise is the only one that really went with Nyssa that I didn't hate. There are others I like more but they just don't go with Nyssa at all.

How is it pronounced?? I read it as "Niss-ah".
I like it.
Yes that is right :-) kind of like Kissa (kisser but with ah sound on end) but with an N instead of a K :-)

short i sound as in Miss :-)
