What I do is to put the full stage name in the Other Nickname(s) field, as I did with actor Vince Edwards:
Zoino-1
This method may not follow our naming guidelines, but I believe we get a better - or at least, more useful - name display with this method.
As many a fellow WikiTreer has mentioned on G2G, our name fields are woefully inadequate.
Don't worry about any suggestions that may occur; you can just mark them false (again, maybe not per our guidelines, but gets the job done).
