Marini
An Italian surname, most likely from the personal name Marino or a family line associated with the sea.
The #8,743 most common surname in the United States (2010 Census) — about 1 in every 82,288 Americans shares it.
Etymology
Marini is an Italian surname formed from Marino, a name ultimately connected with Latin marinus, meaning “of the sea” or “marine.” In Italian surname use, the ending -i often marks a family or plural form, so Marini can suggest “the family of Marino” or “the Marinos.” The deeper root is the Latin word for the sea rather than a direct occupational term.
History
The surname is especially common in Italy and among Italian diaspora communities. It may have arisen independently in several places from the given name Marino, which was popular in Christian and classical naming traditions. Because the name is widespread and longstanding, many separate Marini lines likely exist.
