people will constantly mis-spell and mispronounce it as Frasier - even now when that's not been on properly in years.
Not sure that’s a problem if you happen to be in Scotland. It’s a pretty standard name.
Fraz, is though inevitable. 
I prefer it to Beckett though which either makes me think of the murdered Thomas Beckett or of Samuel Beckett and the trauma I endured studying Endgame at school.
