The wizarding family of Potters descends from the twelfth-century wizard Linfred of Stinchcombe, a locally well-beloved and eccentric man, whose nickname, ‘the Potterer’, became corrupted in time to ‘Potter’. Linfred was a vague and absent-minded fellow whose Muggle neighbours often called upon his medicinal services.
