The History of John Gregg, and his family, of robbers and murderers : Who took up their abode in a cave near to the sea-side, in Clovaley in Devonshire, where they liv'd twenty-five years without so much as once going to visit any city, or town. How they robbed above one thousand persons, and murdered and ate, all whom they robbed. How at last they were happily discover'd by a pack of blood-hounds; and how John Gregg, his wife, eight sons, six daughters, eighteen grand-sons, and fourteen grand-daughters, were all seized and executed, by being cast alive into three fires, and burnt.
