Origin
The surname Patrissi is of Italian origin, with its roots tracing back to the medieval period. It is believed to have originated from the region of Tuscany, where the name was initially found in historical records dating back to the 13th century.
One of the earliest documented instances of the surname Patrissi can be found in the Florentine Codex, a 16th-century ethnographic work describing the culture and history of the Aztec people. This suggests that individuals bearing this surname may have been part of the Italian exploration and colonization efforts in the Americas during that time.
The name Patrissi is thought to be derived from the Latin word "patricius," which means "patrician" or "nobleman." This connection implies that the original bearers of this surname may have been members of the aristocratic class or held positions of authority within their communities.
In the 14th century, a notable figure named Giovanni Patrissi (c. 1320-1390) was a renowned scholar and philosopher from Florence. His works on metaphysics and natural philosophy were widely studied and influential during the Renaissance period.
Another prominent individual with the surname Patrissi was Cesare Patrissi (1510-1592), a Italian Renaissance architect and military engineer. He is best known for his contributions to the fortifications of several cities in Italy, including the design of the Fortezza da Basso in Florence.
In the 18th century, Giacomo Patrissi (1725-1801) was a celebrated Italian painter and engraver. His works were widely admired for their attention to detail and mastery of the chiaroscuro technique, which he employed in his religious and historical paintings.
The Patrissi surname can also be found in various historical documents from the regions of Tuscany and Umbria, such as property records, birth and marriage certificates, and municipal archives. This further reinforces the name's deep-rooted Italian heritage and its association with these regions.
It is worth noting that the spelling of the surname may have evolved over time, with variations such as Patrizi, Patrizzi, or Patrizio being documented in certain historical records. However, the core meaning and origin of the name remained consistent, reflecting its noble and aristocratic connotations.
Demographics
Among Census respondents with the surname Patrissi, the largest self-reported group is White at 92.1%. The next largest groups are Hispanic (2.6%) and Two or More Races (2.6%).
The bar chart below shows how Patrissi 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 Patrissi 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.
