May is a surname of considerable antiquity within the British Isles, recorded in both English and Scottish contexts. Its distribution is chiefly associated with England, although it also appears in Scotland and other regions of the United Kingdom. The name is Christian in religious affiliation, reflecting the predominant faith of the societies in which it developed.
The etymology of May is multifaceted. One line of origin derives from the Old English noun maeg, denoting a “kinsman” or “relative”. In this sense the surname would have functioned as an identifier of familial relationship. A second Old English source is the word mai, meaning “maiden” or “young woman”, which could have been employed as a nickname for a youthful or unmarried individual. A further Scottish derivation links May to the Gaelic MacBheatha, “son of life”, a variant of the surname MacBeth. Thus the surname may reflect either kinship, youth, or a patronymic connection, depending on the linguistic lineage.
Medieval documentation attests to the early use of the name. The earliest recorded spelling appears as William Mai in the Pipe Rolls of Norfolk (1167) during the reign of King Henry II. Subsequent examples include William le Mai (1177), Thomas le Mey and Goscelin Mey (1221), and John Meys (1275). Later records list Stephen Mayes (Warwickshire Subsidy Rolls, 1332) and Ann Mays, daughter of Thomas Mays, baptised in London in 1596. These entries demonstrate the surname’s persistence from the twelfth century onward.
Numerous orthographic variants have been reported, including Le May, Maye, Mayes, Mays, Mayze, Mayzes, Mey, Meys, and Lemay. Some scholars suggest that May may serve as a hypocoristic or diminutive of the given name Matthew, itself derived from the Hebrew Matityahu (“gift of God”). When a plural ending is present, the name may function as a patronymic, indicating “son of May”.
The heraldic record includes a coat of arms granted in Sussex circa 1422, described as a red field charged with a fess between eight gold billets, topped by a crest featuring a leopard’s head. This emblem attests to the social standing that some bearers of the surname attained in the late medieval period.
