Origin
Meaning and origin of Norero
The surname NORERO has its origins in Italy, specifically in the northern region of Piedmont. The name can be traced back to the 14th century, when it was first recorded as "Norrero" in the village of Castiglione Torinese, near the city of Turin.
The name NORERO is believed to be derived from the Latin word "norarius," which referred to a maker or seller of combs. This suggests that the earliest bearers of this surname may have been involved in the comb-making trade, a profession that was particularly important in the medieval period.
One of the earliest recorded instances of the NORERO surname can be found in the Libro Verde della Città di Torino, a historical document dating back to the late 15th century. In this record, a certain Giovanni NORERO is listed as a landowner in the city of Turin.
In the 16th century, the NORERO family gained prominence in the nearby town of Chieri, where they were involved in the local silk industry. The name appears in several municipal records from this period, including the birth and marriage certificates of several NORERO family members.
One notable figure from the NORERO family was Pietro NORERO (1522-1591), a successful silk merchant and member of the town council of Chieri. His son, Giovan Battista NORERO (1564-1638), was a respected lawyer and served as a judge in the court of the Duke of Savoy.
In the 17th century, the NORERO surname spread to other parts of Piedmont, as well as to neighboring regions such as Liguria and Lombardy. One prominent NORERO of this era was Giacomo NORERO (1629-1701), a Jesuit priest and scholar who was renowned for his work on the history of the Piedmontese nobility.
Another notable figure was Carlo NORERO (1772-1842), a military officer who served in the Napoleonic Wars and later became a general in the army of the Kingdom of Sardinia. He was awarded several honors for his bravery in battle.
As the NORERO family continued to prosper and expand, the surname also found its way to other parts of Italy and eventually to other countries through emigration. Despite its widespread dispersal, the name NORERO remains closely tied to its Piedmontese roots and the rich history of this region in northern Italy.

The bar chart below shows how Norero 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 Norero 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.
