The surname Diffey is of English provenance and belongs to the class of surnames that developed in the British Isles during the Middle Ages. It is rooted in the Old English lexeme dæge, which translates as “day.” The name was originally used as a nickname for an individual who was notably active during daylight hours or who displayed a sunny disposition, traits that were valued in early English society.

As English society moved toward a more stable and bureaucratic structure in the later medieval period, many descriptive nicknames were adopted as hereditary surnames. The transformation of dæge into Diffey reflects typical phonological changes within the language, where softer consonantal endings came to be favoured in spelling. Such evolution from nickname to fixed family name was common across England between the thirteenth and fourteenth centuries.

Documentary evidence of the surname in its hereditary form appears in parish registers and land charters of the fifteenth and sixteenth centuries, indicating that the name had become established within local communities by that time. While the surname is distinctly English in origin, its exact occupational or geographic associations are not recorded in surviving sources, suggesting that it was primarily a personal epithet rather than linked to a specific profession or place.

In contemporary times, the surname Diffey remains relatively uncommon. It is recognisably English, and its singular spelling is preserved in modern civil registration records. The persistence of the name through successive generations demonstrates the endurance of medieval naming practices within English genealogy.
