The name Gregory derives from the Greek word ‘gregorious’, meaning to be awake or watchful. The name was borne by two fathers of the early Church and by sixteen popes, starting with the first pope, Gregory the Great in the sixth century.
The Gregory family enter this history in the 1860s when William Moss (1843–1916) married Eliza Gregory. Her family originated from Barking in Essex. The 1881 census shows that half of all Gregorys were living in the northern counties of England, with another large group in London.
