Origin
Meaning and origin of Rebennack
The surname REBENNACK is believed to have originated in the region of Normandy, France, during the Middle Ages, around the 11th or 12th century. It is thought to be derived from the Old French words "rebenne" and "acker," which refer to a type of small boat or raft used for fishing or transportation.
One of the earliest known records of the name dates back to 1198, when a Robert Rebennack was mentioned in a land registry document from the village of Caudebec-en-Caux, near the city of Rouen. This suggests that the name may have initially been associated with individuals who worked on or near the waterways of the region.
In the 13th century, the name appears in several medieval manuscripts and charters from the Normandy area, often spelled as "Rebennacq" or "Rebennacque." This variation in spelling was common during that time, as standardized spellings were not yet widely adopted.
One notable individual with the surname REBENNACK was Jean Rebennack, a French merchant and trader who lived in the port city of Le Havre in the late 15th century (born around 1460). He was known for his involvement in the lucrative trade of wool and textiles between France and England.
Another early bearer of the name was Pierre Rebennack, a soldier who fought in the French army during the Hundred Years' War (1337-1453). Records indicate that he participated in several battles against the English forces, including the Battle of Agincourt in 1415.
In the 16th century, the surname REBENNACK began to spread beyond Normandy, as some families migrated to other parts of France or even other European countries. One such individual was Antoine Rebennack, a Protestant who fled religious persecution in France and settled in Geneva, Switzerland, around 1550.
During the 17th and 18th centuries, the name REBENNACK appeared in various records across different regions of France, with some individuals becoming notable figures in their local communities. For example, in the city of Nantes, there was a family of REBENNACK winemakers who were known for their exceptional vintages.
One of the most prominent figures with the surname REBENNACK was François Rebennack, a French soldier and engineer who served under Napoleon Bonaparte in the early 19th century. He was involved in the construction of several fortifications and military installations during the Napoleonic Wars.
Throughout its history, the surname REBENNACK has maintained a strong connection to its origins in Normandy, even as it has spread to other parts of the world. While not a particularly common name, it continues to be associated with a rich cultural heritage and a legacy of resilience and adaptability.

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