Origin
Meaning and origin of Simonetti
The surname Simonetti is of Italian origin, derived from the given name Simone, which is the Italian form of Simon. This name can be traced back to the late 11th century in various regions of Italy, particularly in the central and northern parts of the country.
Simonetti is a patronymic surname, meaning it was originally formed by adding the suffix "-etti" to the name Simone. This pattern was common in Italian surnames, indicating "son of" or "descendant of." The name may have originated as a way to distinguish different branches of a family that shared the same given name.
One of the earliest recorded instances of the surname Simonetti can be found in the Florentine Priorista, a historical record of the names of the members of the Signoria (the ruling council) of the Republic of Florence. In 1353, a certain Piero di Simone Simonetti is mentioned as holding a position in the council.
In the 14th century, the Simonetti family was prominent in the city of Lucca, where they were involved in the local silk trade. A notable figure from this period was Francesco Simonetti (1330-1405), a wealthy merchant and banker who served as the ambassador of Lucca to the Republic of Venice.
During the Renaissance, the Simonetti family gained prominence in various Italian city-states. In the 15th century, Jacopo Simonetti (1436-1496) was a renowned humanist scholar and diplomat from Pesaro, who served as the secretary to several popes, including Innocent VIII and Alexander VI.
Another notable figure was Girolamo Simonetti (1470-1542), a Sienese jurist and politician who held the position of Capitano del Popolo (Captain of the People) in Siena during the tumultuous years of the Italian Wars. He played a crucial role in defending the city's independence against the imperial forces of Charles V.
In the 17th century, Giovanni Simonetti (1624-1689) was a celebrated architect and engineer from Piedmont. He is best known for his work on the Palazzo Reale in Turin, which he designed in collaboration with other architects.
Throughout history, the Simonetti surname has been found in various regions of Italy, including Tuscany, Emilia-Romagna, Lazio, and Piedmont, reflecting the widespread distribution of this family name across the Italian peninsula.

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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Simonetti surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
