Origin
Meaning and origin of Boror
The surname "BOROR" is believed to have originated in the central region of France during the medieval period, specifically in the area around the town of Bourgoin-Jallieu, located in the department of Isère. It is thought to be derived from the Old French word "boroir," which referred to a specific type of tool used for drilling holes.
One of the earliest recorded instances of the name can be found in the Cartulaire de l'Église de Grenoble, a 13th-century manuscript that contained various legal documents and records. In this manuscript, a person named "Petrus Boror" is mentioned in a land transaction from the year 1248.
During the 14th century, the name appears to have spread to other parts of France, particularly to the northern regions. In the archives of the city of Lille, there are records of a family bearing the name "Boror" who were prominent merchants and traders.
One notable figure with this surname was Jean Boror, a renowned architect and stonemason who lived in the late 15th century. He was responsible for the construction of several churches and cathedrals in the region, including the famous Cathedral of Saint-Étienne in Auxerre, which he worked on from 1476 to 1498.
In the 16th century, the name "Boror" started appearing in records from other European countries, suggesting that members of the family may have migrated or established trade connections abroad. For instance, there are references to a merchant named Matthias Boror who was based in Amsterdam in the 1570s and engaged in the import of French wines.
Another significant figure with this surname was Marie-Madeleine Boror, a French novelist and playwright born in 1683. She was known for her satirical works that often criticized the societal norms and conventions of her time. Her most famous play, "Les Précieuses Ridicules," was a critical success and is still studied in literature courses today.
As the centuries passed, the name "Boror" continued to be found in various historical records across Europe, reflecting the migrations and dispersions of families bearing this surname. However, it is important to note that the name's frequency and distribution may have been influenced by various factors, such as wars, economic conditions, and cultural shifts.
Demographics
Ancestry and ethnicity for Boror

The bar chart below shows how Boror 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 Boror surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
