Meaning:
Its source is Marcus, a Latin name meaning "Dedicated to Mars."
Narrative:
Mars was the Roman war god, equivalent to the Greek god Ares.
Though Marcus (derived from Mars) was certainly a source for this name, a Mark from the Netherlands drew our attention to an Ancient Germanic influence as well.
Terms for boundaries in various Germanic languages, such as the Old English mearcs, gave rise to the French surname (and title) Marquis, and the surnames Marks, Marx and March among the English, German and Dutch. Those surnames and their sources undoubtedly contributed to the emergence of Mark as a personal name.
Borders being traditional points of conflict, it is fitting that words with such a meaning should converge with the name of the Roman god of war to give us the modern name Mark.
