First thought, the American boxing legend
Joe Frazier, as far as I can remember is the pronunciation FRAY-see-er.
Do you mean something maybe like this?
For me personally there would be a difference in pronunciation, Fraser=Fray-zer &
Frasier=Fray-see-er, in any case not Fray-czar. (That would be something like this: Frasar)
I like
Fraser Jamison quite well, maybe also
Fraser Tennyson,
Fraser Donovan.
