Origin
The surname Musmanno is of Italian origin, originating in the town of Musmano, located in the province of Brescia in the Lombardy region of northern Italy. The name is believed to have derived from the Latin word "mus," meaning mouse, and "manno," which is a variation of the word "magnus," meaning great or large. This suggests that the name may have originally referred to someone who lived in an area with a large population of mice.
The earliest recorded instance of the Musmanno surname can be traced back to the 13th century, where it appears in historical records from the town of Musmano. The name was initially spelled as "Musmanno" or "Musmannus," reflecting its Latin roots.
In the 14th century, the Musmanno family gained prominence in the region, with several members holding positions of power and influence in local government and the Catholic Church. One notable figure was Giovanni Musmanno, who served as the Bishop of Brescia from 1349 to 1370.
As the Musmanno family dispersed throughout Italy and beyond, the surname underwent various spelling variations, including Musmanno, Musmano, and Mussmano. These variations can be found in historical records and documents from different regions of Italy.
One of the earliest recorded instances of the Musmanno surname outside of Italy is found in the Doomsday Book, a comprehensive survey of land ownership in England commissioned by William the Conqueror in 1086. The name appears as "Musmano," indicating the presence of an individual or family with that surname in England during the Norman conquest.
Throughout history, several notable individuals have carried the Musmanno surname, including:
1. Michael A. Musmanno (1897-1968), an Italian-American jurist who served as an Associate Justice of the Pennsylvania Supreme Court from 1957 to 1968.
2. Giacomo Musmanno (1674-1748), an Italian painter and architect who worked in the Baroque style and was active in the Marche region of Italy.
3. Giovanni Battista Musmanno (1746-1827), an Italian painter and engraver from Brescia, known for his religious paintings and portraits.
4. Salvatore Musmanno (1891-1973), an Italian-American lawyer and judge who served as a naval officer during World War I and as a judge in Allegheny County, Pennsylvania.
5. Vincenzo Musmanno (1870-1948), an Italian politician and journalist who served as a member of the Italian Parliament and was involved in the Italian Nationalist movement.
While the Musmanno surname has its roots in Italy, it has spread to various parts of the world, including the United States, Canada, and Argentina, as a result of immigration and migration patterns over the centuries.
Demographics
Among Census respondents with the surname Musmanno, the largest self-reported group is White at 89.7%. The next largest groups are Hispanic (7.5%) and Two or More Races (1.9%).
The bar chart below shows how Musmanno 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 Musmanno 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.
