What is the surname of Roger the Dodger from the UK comic 'The Beano'?

Roger the Dodger, whose real name is Roger Dawson, is a fictional character featured regularly in the UK comic 'The Beano'. His strip consists solely of Roger's basic remit to avoid doing chores and homework which usually involves him concocting complex and ultimately disastrous plans, the undoing of which results in him being punished (usually by his long-suffering father). To perform these tasks he enlists the help of his many 'dodge books'.

Roger is a crafty-looking ten-year-old boy who sports a red-and-black chequered jersey with a white shirt collar poking out. He is also usually attired in a white tie, however, the Barrie Appleby strips dropped this around 2005. Upon his debut, Roger sported the usual school boy shorts, however he began wearing trousers during the 1970s.

Roger, unlike most Beano characters, does not go out of his way to cause chaos and mayhem. Instead, he chooses to watch from the sidelines, dodging responsibilities and punishments.
