Some of us outthere probably like a name that is unique, something that stands out (from others). I'm not sure if there is some kind of law or cultural rules that strictly says 'last names should never be used as a first name'. Or, perhaps in some countries, you'd be mocked at if you'd use a last name as a first name?
A friend of mine uses such a last name as his first name: Stravinsky (Stra-vin-ski). Yes, it addresses my mind to think of our famous Russian-American composer, Sir Igor Stravinsky.
What do you think?
