Origin
Meaning and origin of Antonietti
The surname Antonietti has its roots in Italy, specifically in the northern regions of Lombardy and Piedmont. It is believed to have emerged in the 13th or 14th century, derived from the medieval Italian personal name Antonio, itself a variant of the Latin name Antonius. Antonietti is a patronymic surname, meaning it was initially used to denote "son of Antonio" or "descendant of Antonio."
One of the earliest recorded instances of the surname Antonietti can be found in the historic records of the city of Milan, where a certain Petrus Antonietti was listed as a resident in the year 1387. Several other mentions of individuals bearing this surname can be traced back to various towns and villages in the surrounding areas during the 14th and 15th centuries.
Notably, the Antonietti family had a presence in the small town of Castellamonte, in the province of Turin, Piedmont. Historical documents from the 16th century refer to a prominent member of the local nobility, Gaspare Antonietti, who served as a magistrate and held significant influence in the region.
In the 17th century, a branch of the Antonietti family migrated to the nearby city of Ivrea, where they established themselves as respected artisans and merchants. One notable figure from this era was Giovanni Battista Antonietti (1635-1711), a skilled goldsmith whose intricate creations were highly sought after by the local aristocracy.
Another distinguished individual bearing the Antonietti surname was Tommaso Antonietti (1768-1842), a renowned architect and engineer from Milan. He was responsible for the design and construction of several notable buildings and infrastructure projects throughout northern Italy during the late 18th and early 19th centuries.
In more recent history, the name Antonietti gained further recognition with the accomplishments of Carlo Antonietti (1892-1972), a celebrated Italian sculptor and medalist. His works can be found in various museums and public spaces throughout Italy and other parts of Europe.
It is worth noting that variations in spelling, such as Antonetti, Antonetti, and Antonetti, have also been observed in historical records, reflecting the regional differences and dialects within Italy. Additionally, the name Antonietti has been associated with certain place names, such as the town of Antognetta in the province of Bergamo, which may have influenced its formation and spread.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
