 Upon their return to Leicestershire after the revolution they initially appear to have targeted Beler's lands at Kirby Bellars and elsewhere but within a few years petitions were issued to the Sheriff of Nottingham, 'complaining that two of the Folville brothers were roaming abroad again at the head of a band, waylaying persons whom they spoiled and held to ransom'.Various indictments from the period portray Eustace and his brothers as freelance mercenaries, hired 'by the ostensibly law-abiding...to commit acts of violence on their behalf'.Members of Sempringham Priory and Haverholm Abbey, both in Lincolnshire, seem to have made use of their services, and at one stage they were under the patronage of Sir Robert Tuchet, a major lord of Derbyshire and Cheshire.
