Its also an abreviation of Michael, probably the most common one used here and Britan. My son is chrisened Michael but has never been called anything else but Mick. I think over there you might use Mike opposed to Mick.

Mick directed at the irish is aimed more at the catholic section where as Paddy is used as a more inclusive term

Hows that for going off topic, Jeff started it LOL

So David you are probably looking at an irish catholic owner who spent most of his life in Australia, boy of that gun could talk
