Meaning & origin

Marnell is a rare given name in the United States, first recorded in 1919 according to Social Security data. It reached its peak popularity in 1936, after which usage declined sharply. The trajectory of the name has been stable in recent years, remaining largely out of the top 1,000. Marnell's etymology is uncertain; it may be a variant of Marcellus or a transferred surname. The name's sound and structure align with mid-20th-century naming trends, and its obscurity gives it a distinctive quality. No top states or similar names are recorded in the data, reinforcing its rarity.

Marnell is a name of uncertain origin. It may derive from the Roman name Marcellus, a diminutive of Marcus, or it could be an Anglicized form of Irish Ó Muirneáin. Another possibility is that it originated as a surname, perhaps from a place name or as a variant of Marnel. The name saw modest use in the United States in the early to mid-20th century, particularly in the 1930s when it reached its peak popularity.
