Origin
The surname Ianello originated in Italy, specifically in the region of Campania. It is believed to have emerged during the Middle Ages, around the 12th or 13th century. The name is a diminutive of the Italian given name "Iano," which is derived from the Latin name "Ianus," meaning "door" or "passage."
The earliest recorded instances of the surname Ianello can be found in various historical documents from the medieval period in southern Italy. One notable example is the mention of a certain Pietro Ianello in a legal document from the city of Naples, dated around 1285. This suggests that the name was already established in the area by the late 13th century.
In the 14th century, the name appears in records from the town of Capua, which was a prominent center of trade and commerce during the Middle Ages. A merchant named Nicola Ianello is mentioned in a trading contract from 1342, indicating that the name was associated with the mercantile class of the time.
The surname Ianello has also been connected to several place names in the region of Campania. For instance, there is a small village called Ianello located in the province of Benevento, which may have contributed to the spread of the name in the area.
Throughout history, several individuals bearing the surname Ianello have achieved notable recognition. One prominent figure was Girolamo Ianello (1506-1587), a Renaissance painter from Naples who was known for his religious works and frescoes adorning various churches in the city.
Another notable bearer of the name was Francesco Ianello (1700-1778), a composer and violinist from Naples who contributed to the development of the Neapolitan school of violin playing during the Baroque period.
In the 19th century, Antonio Ianello (1820-1892) was a prominent lawyer and politician in Naples, serving as a member of the Italian Parliament and advocating for the unification of Italy.
In the literary realm, Vincenzo Ianello (1878-1965) was an Italian poet and journalist who was part of the Neapolitan literary movement known as the "Poeti della Vigna."
Finally, in the field of science, Mario Ianello (1920-2001) was an Italian mathematician and academic who made significant contributions to the study of algebraic topology and functional analysis.
Demographics
Among Census respondents with the surname Ianello, the largest self-reported group is White at 97.2%. The next largest groups are Black (1.9%) and Two or More Races (0.9%).
The bar chart below shows how Ianello 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 Ianello 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.
