In 1928 his son Harold was injured in the Mitcham Council Stores Yard:
Harold Mount, aged 22, of Church Road. Mitcham, the son of Mr. Harry Mount, Mitcham magistrate, had a remarkable escape from death on Saturday. He was standing near a steam roller under repair in Mitcham Council stores yard, when one of the rear wheels, weighing 30 cwt., fell off and pinned him by the right leg. It required half dozen men with crowbars to release Mr. Mount, who was taken to Nelson Hospital, Merton, with a fractured right leg.
