The surname Driffill was first found in Gloucestershire, in the parish of Driffield or in either Great Driffield or Little Driffield in the East Riding of Yorkshire. Collectively all of the parishes date back to the Domesday Book of 1086 but with older spellings: Drifelle, Gloucestershire; and Drifield, Yorkshire. Each had essentially the same meaning: "open land characterized by dirt, or by stubble," from the Old English words "drit" or "drif" + "feld." 
Conjecturally, the surname is descended from the tenant of the lands of Driffield which was held by Reinbald the Priest, a Norman under-tenant, who was recorded in the Domesday Book census of 1086. Being a priest didn't preclude offspring at that time.
