Marene is of Latin origin, derived from the Roman family name Marenus. It is composed of two elements: "marius," meaning "of Mars," the Roman god of war; and "-enus," a suffix indicating belonging to or associated with. Therefore, Marene could be interpreted as "belonging to Mars" or "associated with Mars." In some instances, it may also be derived from the feminine form of the Latin name Marinus, which means "of the sea.
"Marene experienced a significant increase in popularity between the late 1940s and early 1950s, with the highest number of births occurring in 1947 (13). However, it remained relatively uncommon throughout most of its history, with fewer than 10 births recorded in any given year."
