Origin
Meaning and origin of Brumaire
The surname "BRUMAIRE" is of French origin, traced back to the late 18th century during the French Revolutionary era. It derives from the French word "brumaire," meaning "fog" or "mist," which was the name given to the second month of the French Republican calendar.
The name "BRUMAIRE" is closely associated with the Coup of 18 Brumaire, a significant historical event that took place on November 9-10, 1799 (18-19 Brumaire, Year VIII in the French Republican calendar). This coup d'état, led by Napoleon Bonaparte, marked the end of the French Revolution and the beginning of Napoleon's rise to power.
One of the earliest recorded instances of the surname "BRUMAIRE" can be found in the aftermath of the Coup of 18 Brumaire, when Napoleon Bonaparte appointed several individuals to key positions in his new government. One notable figure was Charles-François Lebrun (1739-1824), who was appointed as the Third Consul of France and served in this role until 1804.
Another historical figure with the surname "BRUMAIRE" was François-Paul Brunet de la Renaudière (1761-1840), a French military officer who fought in the Napoleonic Wars and was later made a Baron of the French Empire by Napoleon in recognition of his service.
During the 19th century, the surname "BRUMAIRE" appeared in various French documents and records, including birth, marriage, and death registers. One notable individual from this period was Pierre-Gaspard Brumaire (1800-1871), a French painter and lithographer known for his landscapes and architectural works.
In the 20th century, the surname "BRUMAIRE" continued to be present in France, although it remained relatively uncommon. One notable figure was Jean-Pierre Brumaire (1915-2008), a French author and journalist who wrote extensively on political and social issues.
Another individual of note was Jacques Brumaire (1921-2012), a French lawyer and politician who served as a member of the National Assembly and held various government positions throughout his career.
While the surname "BRUMAIRE" is not as widespread as some other French surnames, it holds a significant place in French history, particularly due to its association with the Coup of 18 Brumaire and Napoleon Bonaparte's rise to power. The name serves as a reminder of a pivotal moment in the French Revolutionary era and the transition to the Napoleonic era.

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.
