Of the sea; warlike
Marshay is a modern American invention, likely created by combining the prefix 'Mar-' (found in names like Marcia or Mary) with the popular suffix '-shay'. While its exact etymology is fluid, it is often associated with the Latin 'maris' meaning 'of the sea' or 'Mars', the Roman god of war.
