↑Roberts, Damion (5 February 2015). "Interview: Former referee Graham Poll on his return to action at Hitchin Town". The Comet (Stevenage: Archant). Retrieved 10 November 2015. Poll was born in Hitchin and went to Thomas Alleyne School in Stevenage, before taking up refereeing locally in both the Hitchin Sunday and the Stevenage Sunday League. He had moved to Tring, and then to Reading, so being born in the town 'didn’t really come up; I wasn’t seen as having any particular allegiance.'
