Origin
The surname Bomar is believed to have originated in France during the medieval period, likely in the 12th or 13th century. It is thought to be derived from the Old French word "bomer," which means "to thunder" or "to make a loud noise." This could potentially indicate that the name was initially given as a nickname to someone with a booming voice or a particularly loud demeanor.
One of the earliest recorded instances of the name Bomar can be found in the Cahier des États de Normandie, a historical document from the 14th century that lists various landowners and noblemen in the region of Normandy. It is possible that the name's origins can be traced back to this area of northern France.
Throughout the centuries, variations in the spelling of the surname have emerged, such as Bommard, Bomard, and Bomart, though Bomar remains the most commonly used form. These variations likely arose due to regional dialects and inconsistencies in record-keeping.
In the 15th century, a notable figure bearing the name Bomar was Jean Bomar, a French soldier and military commander who fought in the Hundred Years' War. He was recorded as leading a contingent of archers and infantry at the Battle of Agincourt in 1415.
Another historically significant individual with this surname was Pierre Bomar, a French merchant and explorer who traveled extensively throughout the Mediterranean region in the late 16th century. His detailed accounts of his travels and encounters with various cultures were published in a book titled "Voyages et Découvertes" in 1598.
In the 17th century, a man named Étienne Bomar gained recognition as a skilled artisan and goldsmith in the city of Paris. His intricate metalwork and jewelry designs were highly sought after by the French nobility and can still be found in various museums and private collections.
During the 18th century, a French playwright and poet named Philippe Bomar gained some renown for his satirical works that often criticized the excesses of the aristocracy. His most famous play, "Le Bourgeois Gentilhomme," was performed in Parisian theaters in the 1750s.
Another notable figure was Marie-Antoinette Bomar, a French noblewoman and philanthropist who lived during the late 18th and early 19th centuries. She was known for her charitable efforts, particularly her support for orphanages and schools for underprivileged children in Paris.
Demographics
Among Census respondents with the surname Bomar, the largest self-reported group is White at 73.5%. The next largest groups are Black (18.0%) and Two or More Races (4.2%).
The bar chart below shows how Bomar 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 Bomar 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. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
