tregoni

Tregoni is a surname of Italian origin. It is relatively uncommon and is most frequently found in historical records from northern and central Italy.

The etymology of Tregoni is not definitively established. It likely derives from a toponym or a given name, with the suffix -oni characteristic of many Italian surnames that signal patronymic or augmentative meaning.

Geographic distribution and migration patterns show concentrations of the name in regions such as Lombardy, Veneto, and Emilia-Romagna, with later movements to other parts of Italy and to the Americas during the late 19th and early 20th centuries.

In modern reference works, Tregoni is considered a rare surname with limited prominent public figures; most bearers are documented in local genealogical records, civil registries, or parish archives.
