It was also an occupational name for a medieval court officer responsible for the custody of prisoners.

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’.

This is a byname, meaning ‘woman from Magdala’ (a village on the Sea of Galilee, deriving its name from Hebrew migdal ‘tower’), denoting the woman cured of evil spirits by Jesus (Luke 8:2), who later became a faithful follower. In Christian folk belief she was generally identified with the repentant sinner who washed Christ’s feet with her tears in Luke 7; hence the name came to be used as a byname for a prostitute, also a tearful woman. The popularity of the personal name increased with the supposed discovery of her relics in the 13th century.
