Origin
The surname BISNAR is believed to have originated in the region of Catalonia, located in the northeastern part of Spain. It is thought to derive from the Catalan word "bisner," which means "nephew" or "grandson." This suggests that the name may have initially been a descriptive surname, possibly referring to someone's relationship within a family or clan.
The earliest known record of the BISNAR surname dates back to the 13th century. In 1246, a document from the city of Barcelona mentioned a certain "Pere Bisner," which is likely one of the earliest written instances of this surname.
During the Middle Ages, surnames were not yet widely established, and people were often identified by their occupation, location, or physical characteristics. As such, the BISNAR name may have initially referred to a specific individual's familial relationship before becoming a hereditary surname.
One notable historical figure bearing the BISNAR surname was Guillem Bisner, a Catalan merchant and trader who lived in the 14th century. Records show that he was involved in the lucrative Mediterranean trade routes, transporting goods between Barcelona and various ports in Italy and North Africa.
In the 16th century, the BISNAR surname appears to have spread beyond Catalonia, with records indicating individuals bearing this name in other parts of Spain, as well as in parts of Portugal and southern France.
Another notable individual with the BISNAR surname was Jaume Bisnar, a Catalan painter who lived in the late 17th century. He is known for his religious paintings and frescoes that adorned several churches and monasteries in Barcelona and its surrounding areas.
As the centuries passed, the BISNAR surname continued to be present in various regions of Spain and beyond. In the 19th century, Juan Bisnar, a Spanish military officer, played a role in the Spanish-American War, serving in the Spanish forces stationed in Cuba.
Additionally, María Bisnar, born in 1842 in Valencia, Spain, was a renowned educator and advocate for women's rights. She established several schools for girls and campaigned for equal educational opportunities for women in Spain during a time when such efforts were highly progressive.
While the BISNAR surname may have originated as a descriptive term related to family relationships, it eventually became a hereditary surname carried by individuals from diverse backgrounds and occupations, leaving a lasting mark on the historical record of Spain and other parts of the world.
Demographics
Among Census respondents with the surname Bisnar, the largest self-reported group is Asian/Pacific Islander at 69.7%. The next largest groups are White (17.2%) and Two or More Races (7.1%).
The bar chart below shows how Bisnar 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 Bisnar 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.
