Of the sea or warlike
Marico is a rare name with dual potential etymologies. It is often considered a variant of Marius, a Roman family name likely derived from Mars, the Roman god of war, or from the Latin 'mare' meaning sea. In some contexts, it is used as a masculine form of Maria or a variation of the Japanese name Mariko, though it remains extremely uncommon in the United States.
