Origin
The surname ACELLO has its origins in Southern Italy, primarily in the regions of Campania and Basilicata. The name can be traced back to the late medieval period, around the 13th or 14th century.
ACELLO is believed to be derived from the Latin word "acellus," which means "little field." This suggests that the name may have originally referred to someone who lived near or owned a small field or plot of land.
One of the earliest recorded instances of the name ACELLO can be found in a monastic record from the town of Amalfi, dating back to the late 14th century. This record mentions a certain Nicola Acello, who was a member of a local noble family.
In the 15th century, the name ACELLO appeared in several legal documents and deeds from the town of Potenza, in the Basilicata region. These documents reference various individuals, such as Giovanni Acello (born around 1420) and Antonio Acello (born around 1450), who were involved in land transactions and disputes.
During the Renaissance period, there are records of a prominent family bearing the name ACELLO in the city of Naples. One notable member was Gian Battista Acello (1493-1567), a renowned sculptor and architect who contributed to the design of several churches and palaces in Naples.
In the 17th century, a branch of the ACELLO family migrated to the island of Sicily, where they established themselves as landowners and merchants. One well-known figure from this era was Vincenzo Acello (1621-1693), a wealthy merchant and philanthropist who funded the construction of a hospital in the city of Palermo.
Throughout the 18th and 19th centuries, the ACELLO surname continued to be present in various parts of Southern Italy, with families residing in towns and villages across Campania, Basilicata, and Calabria. One notable individual from this period was Giuseppe Acello (1785-1862), a lawyer and political activist who played a role in the Italian unification movement.
Demographics
Among Census respondents with the surname Acello, the largest self-reported group is White at 91.3%. The next largest groups are Hispanic (4.9%) and Black (1.9%).
The bar chart below shows how Acello 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 Acello 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.
