Gilbert
Gilbert was the groundskeeper at the school and as such lived in a shed between the pavilion and the cricket-scoring hut. (it was a middle class school in surrey that had pretensions towards some sort of Brideshead revisited idyll).
Naturally it was assumed that he molested children in the shed. Anyone suspected of kiddy fiddling was known as a Gilbert.
