English and Dutch : from Latin Marcus, the personal name of St. Mark the Evangelist, author of the second Gospel. The name was borne also by a number of other early Christian saints. Marcus was an old Roman name, of uncertain (possibly non-Italic) etymology; it may have some connection with the name of the war god Mars. Compare Martin. The personal name was not as popular in England in the Middle Ages as it was on the Continent, especially in Italy, where the evangelist became the patron of Venice and the Venetian Republic, and was allegedly buried at Aquileia. As an American family name, this has absorbed cognate and similar names from other European languages, including Greek Markos and Slavic Marek.English, German, and Dutch (van der Mark) : topographic name for someone who lived on a boundary between two districts, from Middle English merke, Middle High German marc, Middle Dutch marke, merke, all meaning ‘borderland’.

English, Welsh, German, etc.
English, Welsh, German, etc. : ultimately from the Hebrew personal name yÅÌ£hÄnÄn ‘Jehovah has favored (me with a son)’ or ‘may Jehovah favor (this child)’. This personal name was adopted into Latin (via Greek) as Johannes, and has enjoyed enormous popularity in Europe throughout the Christian era, being given in honor of St. John the Baptist, precursor of Christ, and of St. John the Evangelist, author of the fourth gospel, as well as others of the nearly one thousand other Christian saints of the name. Some of the principal forms of the personal name in other European languages are Welsh Ieuan, Evan, Siôn, and Ioan; Scottish Ia(i)n; Irish Séan; German Johann, Johannes, Hans; Dutch Jan; French Jean; Italian Giovanni, Gianni, Ianni; Spanish Juan; Portuguese João; Greek IÅannÄ“s (vernacular Yannis); Czech Jan; Russian Ivan. Polish has surnames both from the western Slavic form Jan and from the eastern Slavic form Iwan. There were a number of different forms of the name in Middle English, including Jan(e), a male name (see Jane); Jen (see Jenkin); Jon(e) (see Jones); and Han(n) (see Hann). There were also various Middle English feminine versions of this name (e.g. Joan, Jehan), and some of these were indistinguishable from masculine forms. The distinction on grounds of gender between John and Joan was not firmly established in English until the 17th century. It was even later that Jean and Jane were specialized as specifically feminine names in English; bearers of these surnames and their derivatives are more likely to derive them from a male ancestor than a female. As a surname in the British Isles, John is particularly frequent in Wales, where it is a late formation representing Welsh Siôn rather than the older form Ieuan (which gave rise to the surname Evan). As an American family name this form has absorbed various cognates from continental European languages. (For forms, see Hanks and Hodges 1988.)

English : habitational name from any of several places so called, named with the genitive plural huntena of Old English hunta ‘hunter’ + tūn ‘enclosure’, ‘settlement’ or dūn ‘hill’ (the forms in -ton and -don having become inextricably confused). A number of bearers of this name may well derive it from Huntingdon, now in Cambridgeshire (formerly the county seat of the old county of Huntingdonshire), which is named from the genitive case of Old English hunta ‘huntsman’, perhaps used as a personal name, + dūn ‘hill’.A prominent American family of this name were founded by Simon Huntington, who himself never saw the New World, for he died in 1633 on the voyage to Boston, where his widow settled with her children. Their descendants include Jabez Huntington (1719–86), a wealthy West Indies trader, and Samuel Huntington (1731–96), who was one of the signers of the Declaration of Independence. Collis Potter Huntington (1821–1900) was an American railway magnate. Beginning with little education or money, he made a huge fortune, some of which he left to his nephew, Henry Huntington (1850–1927), who used the money to establish the Huntington library and art gallery in CA.

English : habitational name from a place in Cumbria (Westmorland). The place name is recorded in Domesday Book as Lupetun, and probably derives from an Old English personal name Hluppa (of uncertain origin) + Old English tūn ‘enclosure’, ‘settlement’.The name was brought to America by John Lupton, who sailed from Gravesend, England, on the Primrose in 1635, and is recorded in VA three years later. On 24 October 1635 Davie Lupton set off on the Constance bound for VA, but there is no record of his arrival in the New World. A Christopher Lupton is recorded in Suffolk Co., Long Island, NY, c.1635, and a large number of Luptons in NC descend from him. An American family of the name settled in the area of Winchester, VA, in the mid18th century; they can be traced back to Martin Lupton, who was married in 1630 in the parish of Rothwell, Yorkshire, England.
