FBI Files report that the surname ‘Crooks’ is an ancient English surname relating to an individual who specialises in the care of adult sheep or juvenal lambs. As a surname, it is related to the surnames ‘Shepperd’ and ‘Lambert’ – with ‘Crooks’ referring to a six-foot wooden staff that possess a ‘hook’ (or ‘crook’) at one-end – used to ‘envelop’ the neck-area of a sheep or lamb – ‘at a distance’. This piece of pre-modern technology allows for troublesome and quick-footed sheep and lambs that need to be captured and brought near to their human carer.
