Marcelli / Marcellus / Marcel / Marcello

Marcelli is a surname and a given name derived from the Roman family name Marcellus. Marcellus itself is a diminutive of Marcus, which is thought to be derived from Mars, the Roman god of war. The name has been used in various forms throughout European history, particularly in Italy and other Romance-speaking countries. As a given name, it has historically been more common for males, but its use as a surname has led to its occasional adoption as a unisex given name, especially in modern times where gender boundaries for names are more fluid.
