Warlike; dedicated to Mars
Marcas is the Irish and Scottish Gaelic form of the Latin name Marcus. It is etymologically rooted in Mars, the Roman god of war, signifying a warrior spirit or one who is dedicated to the deity. While Marcus is a perennial classic, Marcas offers a distinct Celtic flair for parents seeking a heritage-focused alternative.
Fewer than 5 boys were named Marcas in 2025.
