Marra
A surname with several possible roots, including an old Irish family name and a separate Italian or Latin-like name source.
The #5,719 most common surname in the United States (2010 Census) — about 1 in every 50,906 Americans shares it.
Etymology
The surname Marra is not straightforwardly traced to one single origin. In Irish contexts, the historical material connects it with the Macnamara line, ultimately from a Gaelic personal name interpreted as meaning something like “sea hero.” Separately, other surname dictionaries note a possible derivation from Latin or Italian forms such as marra, meaning a mattock or pick-axe, though this was already treated as doubtful by 19th-century scholars.
History
The sources point to more than one surname tradition behind the spelling Marra. In Ireland, it may be associated with the broader Macnamara family of County Clare, while in other European settings it may have developed independently from a nickname or occupational term. Because the same spelling can arise in different languages, modern bearers of the surname may not share a single ancestral origin.

Fun fact
A 19th-century etymology book explicitly listed several possible explanations for Marra and refused to settle on just one, which is a good reminder that surname origins are not always neat or singular.
