Origin
The surname Marzetti originated in Italy, specifically in the regions of Tuscany and Emilia-Romagna, during the Middle Ages. It is believed to be derived from the Italian word "marzo," meaning "March," suggesting a possible connection to someone born or associated with that month. Alternatively, it could also stem from the Latin word "martius," which has the same meaning.
One of the earliest recorded instances of the Marzetti name can be found in a document from the 14th century, where a certain Guglielmo Marzetti is mentioned as a landowner in the city of Bologna. This suggests that the name had already established itself in the area by that time.
In the 15th century, the Marzetti family gained prominence in the city of Florence, where they were involved in the wool trade and banking industries. Historical records show that members of the family held influential positions within the city's guilds and governing bodies.
During the Renaissance period, the Marzetti name was associated with several notable figures. One such individual was Giovanni Marzetti (1499-1564), a renowned Italian architect who designed several churches and palaces in the city of Ferrara, including the Church of San Guglielmo and the Palazzo dei Diamanti.
Another notable bearer of the Marzetti name was Antonio Marzetti (1601-1678), a philosopher and theologian who taught at the University of Bologna. His works on ethics and metaphysics were widely studied and influential during his time.
In the 18th century, the Marzetti family continued to play a role in Italian society. Pietro Marzetti (1712-1778) was a prominent lawyer and judge who served as a magistrate in the city of Modena. His nephew, Giuseppe Marzetti (1756-1821), was a respected physician and author who wrote several treatises on medical topics.
As the centuries progressed, members of the Marzetti family spread throughout Italy and beyond. Some notable individuals include the Italian-American entrepreneur Teresa Marzetti (1899-1972), who founded the Marzetti Company, which produces salad dressings and other food products, and the Italian film director Enrico Marzetti (1922-2004), known for his work in the genre of commedia all'italiana.
Demographics
Among Census respondents with the surname Marzetti, the largest self-reported group is White at 86.4%. The next largest groups are Hispanic (8.2%) and Black (2.7%).
The bar chart below shows how Marzetti bearers described their own race and ethnicity on the 2020 Census form. 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 Marzetti surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
