The English surname Gregory is of patronymic origin being derived from a personal name that was popular throughout Christendom in the Middle Ages. The Greek original, Gregorios, is a derivative of gregorein ‘to be awake’, ‘to be watchful’. However, the Latin form, Gregorius, came to be associated by folk etymology with grex, gregis, meaning ‘flock or herd,”under the influence of the Christian image of the good shepherd. The first recorded reference, is believed to be that of Willelmus Gregorii, in the charters known as "The Danelaw" for the county of Lincoln, England, in the year 1143. Another early reference was John Grigory, in the Assize Rolls of the county of Somerset for the year 1280.
