Mariani

Mariani is a surname of Italian origin, derived from the given name Marius. The suffix '-ani' is a common patronymic or locative ending in Italian surnames, indicating 'descendant of' or 'belonging to'. The name Marius itself is an ancient Roman nomen gentile (family name) of uncertain etymology, possibly related to Mars (the Roman god of war), or to the Latin word 'mas' (male). Over time, the surname Mariani became established in various regions of Italy.

While primarily a surname, in some cultures, particularly those influenced by Italian naming conventions, surnames can occasionally be adopted as given names, though this is less common for Mariani as a first name. Its usage as a given name is rare and often occurs in contexts where a family surname is passed down as a first name to honor an ancestor.
