Winston Smith is the central character of 1984, and there was a tv show in the 1980s called 'Citizen Smith' about a left wing Londoner called Wolfie Smith.
The two are probably a paly on words by the writers, rather than a direct attribution. Big Brother and Room 101 are directly and purposefully taken from the novel.
Your teacher may give you a bonus point if you tell him/her that Terry Gilliam (the American member of 'Monty Python', cartoonist and film director) based his comic film 'Brazil' on 1984, additional to the film version of the original book, starring John Hurt.
