Hugh Oswald is a hedge wizard, formerly employed by the Folly. He fought at Antwerp and Ettersberg during World War II. After the war he retired to the countryside, to the town of Leominster in Herefordshire, and became a beekeeper. He gave his staffs to Peter Grant.
He has a copy of the book Folklore of Herefordshire by Ella Mary Leather, probably stolen from Gloucester City Library, in his private library.
He is the grandfather of Mellissa Oswald.
