Origin
The surname BISONO is believed to have originated in the northern regions of Italy during the medieval period, around the 12th or 13th century. It is thought to have derived from the Italian word "bisonte," which means "bison" or "buffalo." This suggests that the name may have been initially given as a descriptive nickname to someone who lived near or worked with these animals.
One of the earliest recorded references to the name BISONO can be found in a document from the city of Bologna, dated 1324. This document mentions a certain "Giovanni Bisono," who was a landowner and farmer in the region. It is possible that this individual or his ancestors were involved in the raising or trading of bison or buffalo, which could explain the origin of the surname.
In the 15th century, the name BISONO appeared in several historical records from the town of Verona, indicating that the family had spread to different parts of northern Italy. One notable individual from this era was Bartolomeo Bisono (1427-1493), a respected merchant and banker who played a significant role in the city's economic affairs.
As the centuries passed, the name BISONO continued to be found in various regions of Italy, with some individuals achieving notable status. In the 16th century, there was a renowned painter named Girolamo Bisono (1504-1572) from the city of Venice, whose works can still be found in several Italian museums and churches.
Another prominent figure was Francesco Bisono (1634-1712), a theologian and scholar from Naples who authored several influential books on religious philosophy and ethics. His writings were widely studied and discussed in academic circles throughout Europe during the late 17th and early 18th centuries.
In more recent times, the name BISONO has been carried by individuals such as Giulio Bisono (1892-1965), an Italian politician and lawyer who served as a member of the Italian Chamber of Deputies from 1948 to 1958. Additionally, there was Mario Bisono (1920-2003), a celebrated Italian novelist and poet whose works explored themes of love, loss, and the human condition.
While these are just a few examples, the surname BISONO has a rich history spanning several centuries and regions of Italy. Its origins can be traced back to the medieval era, and it has been borne by individuals from various walks of life, including landowners, merchants, artists, scholars, and political figures.
Demographics
Among Census respondents with the surname Bisono, the largest self-reported group is Hispanic at 96.6%. The next largest groups are White (2.6%) and Black (0.4%).
The bar chart below shows how Bisono 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 Bisono 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.
