Origin
Meaning and origin of Manno
The surname Manno is of Italian origin, with its earliest records dating back to the 12th century in the region of Piedmont, located in northwestern Italy. The name is believed to have derived from the Latin word "mannus," which means "little horse" or "pony." This suggests that the name may have originally been an occupational surname for someone who worked with horses, such as a stable hand or horse breeder.
In the 13th century, the name Manno appeared in various Italian documents, including the Codice Diplomatico della Repubblica di Genova, a collection of diplomatic documents from the Republic of Genoa. One notable early bearer of the name was Giacomo Manno, a merchant from Genoa who lived in the late 13th century and was involved in international trade.
The Manno surname also has historical ties to the island of Sardinia, where it can be traced back to the 15th century. One of the earliest recorded instances of the name in Sardinia was Matteo Manno, a nobleman who lived in the town of Sassari in the late 1400s.
As the Manno family spread throughout Italy, variations in spelling emerged, such as Manni, Mannino, and Mannone. Some of these variations may have been influenced by local dialects or derived from diminutive forms of the name.
Notable individuals with the surname Manno include:
1. Antonio Manno (1834-1918), an Italian historian and politician from Sardinia, known for his work on the history of Sardinia.
2. Giuseppe Manno (1786-1868), an Italian writer and statesman from Piedmont, who served as the Minister of Public Instruction in the Kingdom of Sardinia.
3. Domenico Manno (1723-1785), an Italian painter from Sardinia, known for his religious works and portraiture.
4. Giovanni Manno (1744-1834), an Italian lawyer and writer from Piedmont, who served as a judge and published works on legal topics.
5. Pietro Manno (1785-1864), an Italian scholar and linguist from Piedmont, who studied and documented the Piedmontese language.
While the Manno surname has its roots in Italy, it has since spread to other parts of the world through immigration and can be found among Italian diaspora communities in countries like the United States, Canada, and Argentina.

The bar chart below shows how Manno 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 Manno 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.
