The surname Milsom is of English origin. It is normally regarded as a patronymic or derivation of an older personal name that was used in Anglo‑Saxon and later in medieval England.

One proposed derivation links Milsom to the Old English personal name Mildthryth (or Mildthryð), a compound of mild meaning “gentle” and þryð meaning “strength” or “power”. The name would therefore have conveyed the sense of “gentle strength” or “mild power”. The elements migrate and evolve through the Middle English period, eventually giving rise to forms such as Milsom. This etymology is supported by the record of the surname appearing in the early fifteenth century in the Poll Tax Rolls for Yorkshire where a Thomas Milsson is listed in 1379.

An alternate explanation locates the name in the Germanic personal name Milo, from the Old German element mil meaning “beloved” or “mercy”. This form was introduced into England by the Normans and would have been Latinised or Anglicised as Miles before being passed to its current form Milsom as a patronymic. The earliest recorded spelling of the family name is that of Richard Milleson, a witness in the Assize Rolls of Staffordshire dated 1309, which falls within the reign of King Edward (known conventionally as Edward I from 1272). The persistence of the spelling over centuries suggests a strong local tradition of the name in the Midlands and East Anglia.

Records in the 16th and 17th centuries show the surname and its variants in various civil and ecclesiastical documents. For example, an Anne Melsam married William White at St. Mary Woolchurch Haw in London on 1 April 1594. Thomas Milsom married Margarettam Lloyd on 16 July 1660 at St. Martin-in-the-Fields, Westminster. The hearth tax returns of Suffolk record a Thomas Melson in 1674, illustrating the interchangeable use of the suffix -son and -som during the early modern period.

The name has appeared under several orthographic variations, reflecting the lack of standardised spelling in medieval and early modern England. Notable variants include Millsom, Millson, Millsum, Melsom, Melsome, and Melson. These variations are all recognised as belonging to the same familial line, and they can be traced through genealogical sources such as the Subsidy Rolls of Suffolk (1524) and the Hearth Tax Returns. The diversity of spellings demonstrates the fluid nature of surname formation in English history and provides a valuable avenue for researchers tracing lineages back to the early succession of records in the fourteenth and fifteenth centuries.
