Meaning & origin

Marinus is an exceedingly rare name in the United States, first recorded in 1911 with too few births to register on the Social Security Administration's ranked lists. Its peak year was also 1911, and it has maintained a stable but extremely low trajectory since then, never exceeding a handful of annual births. The name's Latin origin, meaning 'of the sea', connects it to a long European tradition of saints and scholars, yet in America it has never broken into common usage, likely due to its unfamiliar sound and potential confusion with more common names like Marino or Marius. Despite its obscurity, Marinus offers a distinctive choice with a clear etymology and historical depth.

Marinus derives from the Latin 'marinus', meaning 'of the sea', a masculine form of Marina. It was a common Roman cognomen and later adopted by early Christians, including several saints. The name appears in various European languages, often as a Latinized form of local names.
