It was introduced to England by the Normans, for whom it was a popular name among the ruling classes, perhaps partly because of association with Old French lance ‘lance’, ‘spear’ (see 2).French : metonymic name for a soldier who carried a lance, or a nickname for a skilled fighter, from Old French lance.

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’.
