Origin
Meaning and origin of Bornelus
The surname BORNELUS originated in France during the Middle Ages. It is believed to have roots in the Latin word "bornellus," which means "little boundary" or "small limit." This suggests that the name may have been originally given to someone who lived near a boundary or border.
One of the earliest recorded instances of the BORNELUS name can be found in the Cartulaire de l'abbaye de Saint-Père de Chartres, a medieval cartulary from the 12th century. This document mentions a person named Petrus Bornelus, who was likely a landowner or tenant in the region around Chartres, France.
In the 14th century, the name appears in the Livre de la Taille de Paris, a tax record from the city of Paris. This suggests that by this time, families bearing the BORNELUS surname had established themselves in the French capital.
A notable figure with the BORNELUS surname was Jean Bornelus, a French scholar and theologian who lived from 1492 to 1562. He was a prominent figure during the Protestant Reformation and wrote several works on religious doctrine.
Another historical figure was Nicolas Bornelus, a French merchant and explorer who lived from 1540 to 1612. He is known for his travels to the Americas and his accounts of the indigenous peoples he encountered.
In the 17th century, the BORNELUS name can be found in the records of the French colony of Saint-Domingue (now Haiti). This suggests that some members of the family may have emigrated to the Caribbean during this period.
One of the earliest recorded instances of the BORNELUS surname in England dates back to the 16th century, when a family bearing this name settled in the county of Devon. This could indicate that some members of the family may have migrated from France to England during this time.
Throughout history, the BORNELUS surname has also been associated with various place names and locations in France, such as the village of Bornelles in the department of Oise, and the commune of Bourneville in the department of Eure.

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 Bornelus surname at the time of the 2020 Census, not any inherent property of the name itself.
