Origin
The surname Mannerino is believed to have originated in Italy, likely in the region of Tuscany or Umbria, sometime around the 13th or 14th century. It is thought to be derived from the Italian word "mannaro," which means "werewolf" or "shapeshifter." This suggests that the name may have been given as a nickname to someone who was considered fierce or wild in nature.
One of the earliest recorded instances of the name Mannerino can be found in a manuscript from the Tuscan town of Siena, dated around 1320. The document mentions a certain "Guido Mannerino," who was a local landowner and merchant. This suggests that the name was already established in the region by that time.
In the 15th century, a family bearing the name Mannerino was recorded as living in the town of Perugia, in the neighboring region of Umbria. One notable member of this family was Matteo Mannerino (1425-1489), a renowned scholar and philosopher who taught at the University of Perugia.
The name Mannerino also appears in several other historical documents from various parts of Italy, including a census record from the city of Naples in the late 16th century, which lists a "Giovanni Mannerino" as a resident.
Another prominent figure with the surname Mannerino was Girolamo Mannerino (1570-1642), a Neapolitan painter and architect who was known for his work in the Baroque style. He designed several churches and palaces throughout Italy, and his paintings can still be found in various collections and museums.
In the 18th century, a branch of the Mannerino family settled in the city of Genoa, where they became successful merchants and traders. One member of this family, Antonio Mannerino (1735-1802), was a prominent businessman and philanthropist who funded the construction of several public buildings and institutions in the city.
Over the centuries, the name Mannerino has spread to other parts of Italy and beyond, with various spellings and variations emerging, such as Mannarino, Mannerini, and Mannarini. However, the original form of Mannerino remains deeply rooted in the historical and cultural traditions of central and southern Italy.
Demographics
Among Census respondents with the surname Mannerino, the largest self-reported group is White at 90.3%. The next largest groups are Two or More Races (6.8%) and Asian/Pacific Islander (1.9%).
The bar chart below shows how Mannerino 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 Mannerino 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.
