English and Irish : apparently a topographic name from Middle English furlong ‘length of a field’ (from Old English furh ‘furrow’ + lang ‘long’), the technical term for the block of strips owned by several different persons which formed the unit of cultivation in the medieval open-field system of farming, or a habitational name from a minor place named with this word, such as Furlong in Devon or Shropshire. The surname is now chiefly common in Ireland, where a family of this name settled at the end of the 13th century.Possibly an Americanized form of French Ferland.

English and French
English and French : in medieval times this did not denote a rank in the army, but was an occupational name for a servant, Middle English, Old French sergent (Latin serviens, genitive servientis, present participle of servire ‘to serve’). The surname probably originated for the most part in this sense, but the word also developed various more specialized meanings, being used for example as a technical term for a tenant by military service below the rank of a knight, and as the name for any of certain administrative and legal officials in different localities, which may also have contributed to the development of the surname. The sense ‘non-commissioned officer’ did not arise until the 16th century.William Sargent (1624–1717) came to Gloucester, MA, from Devon, England before 1678. Many of his descendants distinguished themselves in the civil and military affairs of the colonies and some in literary or artistic paths, notably the portrait painter John Singer Sargent (1856–1925).
Surname or Lastname
English
English : from Old Norse drengr ‘young man’, but with more than one possible interpretation. It may reflect the personal name (originally a byname) of this form, which had some currency in the most Scandinavian-influenced areas of medieval England. Alternatively it may reflect the Middle English borrowing of the vocabulary word in the sense ‘servant’, later a technical term of the feudal system of Northumbria for a free tenant who held land by military and agricultural service, sometimes paying rent as well or in commutation.

English : occupational name for a keeper of a lodging house, Middle English innmann, from Old English inn ‘abode’, ‘lodging’ + mann ‘man’. Until recently there was in England a technical distinction between an inn, where lodgings were available as well as alcoholic beverages, and a tavern, which offered only the latter.

English : nickname from Middle English, Old French hagard ‘wild’, ‘untamed’. This word was adopted into Middle English as a technical term in falconry to denote a hawk that had been captured and trained when already fully grown, rather than being reared in captivity; the surname may have developed as a metonymic occupational name for a falconer.Americanized form of Danish Ågård (see Agard).

English (of Norman origin)
English (of Norman origin) : via Old French from the Germanic personal name Milo, of unknown etymology. The name was introduced to England by the Normans in the form Miles (oblique case Milon). In English documents of the Middle Ages the name sometimes appears in the Latinized form Milo (genitive Milonis), although the normal Middle English form was Mile, so the final -s must usually represent the possessive ending, i.e. ‘son or servant of Mile’.English : patronymic from the medieval personal name Mihel, an Old French contracted form of Michael.English : occupational name for a servant or retainer, from Latin miles ‘soldier’, sometimes used as a technical term in this sense in medieval documents.Irish (County Mayo) : when not the same as 1 or 3, an Anglicized form of Gaelic Ó Maolmhuire, Myles being used as the English equivalent of the Gaelic personal name Maol Muire (see Mullery).Jewish (eastern Ashkenazic) : unexplained.Dutch : variant of Miels, a variant of Miele 3.John Miles or Myles (c.1621–83), born probably in Herefordshire, England, was a pioneer American Baptist minister who emigrated to New England in 1662 and had a pastorate in Swansea, MA.

English : status name from Middle English frankelin ‘franklin’, a technical term of the feudal system, from Anglo-Norman French franc ‘free’ (see Frank 2) + the Germanic suffix -ling. The status of the franklin varied somewhat according to time and place in medieval England; in general, he was a free man and a holder of fairly extensive areas of land, a gentleman ranked above the main body of minor freeholders but below a knight or a member of the nobility.The surname is also borne by Jews, in which case it represents an Americanized form of one or more like-sounding Jewish surnames.In modern times, this has been used to Americanize François, the French form of Francis.The American statesman and scientist Benjamin Franklin (1706–90) was the son of Josiah Franklin, a chandler (dealer in soap and candles), who had emigrated in about 1682 from Ecton, Northamptonshire, to Boston, MA, where his son was born.

English : nickname from Middle English child ‘child’, ‘infant’ (Old English cild), in various possible applications. The word is found in Old English as a byname, and in Middle English as a widely used affectionate term of address. It was also used as a term of status for a young man of noble birth, although the exact meaning is not clear; in the 13th and 14th centuries it was a technical term used of a young noble awaiting elevation to the knighthood. In other cases it may have been applied as a byname to a youth considerably younger than his brothers or to one who was a minor on the death of his father.English : possibly a topographic name from Old English cielde ‘spring (water)’, a rare word derived from c(e)ald ‘cold’.
