Then McGrath of Harlow chipped in with 'Mc and Mac are the same thing. Except, for Irish names, in Irish it's more common to have it as Mac, and in English as Mc.'

I suggest both of you contact the Sligo musician Shane McGowan to inform him that he's really a singer from Tunbridge Wells!

Seriously, there is a huge linguistic difference between 'Mc' and 'Mac' and one generally reflective of Ireland's convoluted history.
