Origin
Meaning and origin of Coti
The surname COTI has its origins in Northern Italy, specifically in the region of Lombardy. It is believed to have emerged around the 12th century, derived from the Latin word "coctus," which means "cooked" or "baked." This suggests that the name may have initially been associated with occupations related to baking or cooking.
One of the earliest recorded mentions of the COTI surname can be found in a document from the city of Milan, dated 1235. This document refers to a certain "Petrus Coti," indicating that the name was already in use at that time. Another early reference is found in the records of the city of Pavia, where a "Jacobus Coti" is mentioned in 1278.
During the 14th century, the COTI surname began to spread beyond Lombardy to other regions of Northern Italy. In 1367, a "Giovanni Coti" is mentioned in the records of the city of Verona, while in 1392, a "Marco Coti" appears in the archives of the city of Vicenza.
One of the earliest notable individuals with the COTI surname was Antonio Coti (c. 1450 - 1520), a renowned painter and architect from Milan. His works can still be admired in various churches and buildings throughout the region. Another prominent figure was Girolamo Coti (1570 - 1636), a scholar and philosopher from Pavia who wrote extensively on topics ranging from theology to natural sciences.
In the 17th century, the COTI surname gained prominence in the realm of literature. Alessandra Coti (1605 - 1677) was a renowned poet and playwright from Verona, whose works were widely celebrated during her lifetime. Her contemporary, Gian Paolo Coti (1620 - 1692), was a respected historian and author from Milan, known for his comprehensive chronicles of the city's history.
As the centuries progressed, the COTI surname continued to be represented in various fields. In the late 19th century, Giuseppe Coti (1845 - 1921) was a prominent politician and statesman from Lombardy, serving as a member of the Italian parliament for several terms.
While the COTI surname has its roots in Northern Italy, it has since spread to other parts of the world, carried by immigrants and descendants of the original bearers. However, its historical origins and earliest recorded instances can be traced back to the regions of Lombardy and surrounding areas in the 12th and 13th centuries.
Demographics
Ancestry and ethnicity for Coti

The bar chart below shows how Coti 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 Coti surname at the time of the 2020 Census, not any inherent property of the name itself.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
