Origin
The surname Rambo is of French origin, deriving from the Old French word "rambe," which means "wild garlic" or "ramps." This suggests that the name may have initially been an occupational surname given to someone who cultivated or traded in wild garlic.
The name can be traced back to the 12th century in the Normandy region of northern France. One of the earliest recorded instances of the name appears in the Cartulaire de Louviers, a medieval manuscript from the 12th century, where a person named Radulphus Rambo is mentioned.
In the 13th century, the name is found in various forms, such as Ramboud, Ramboude, and Rambault, in documents from the Picardy and Île-de-France regions of northern France. These variations likely stem from the different dialects and spellings used in different areas at the time.
The name Rambo spread across Europe during the medieval period, with records showing individuals bearing this surname in England, Germany, and the Low Countries (present-day Belgium and the Netherlands). In England, the surname is found in the Hundred Rolls of 1273, where a William Rambo is listed as a resident of Oxfordshire.
One of the earliest known bearers of the Rambo surname was Jean Rambo, a French soldier who fought in the Hundred Years' War between England and France in the 14th century. He was born around 1320 in the village of Rambouillett, near Paris.
Another notable individual with this surname was Petrus Rambo, a Dutch scholar and theologian who lived from 1556 to 1628. He was born in Middelburg, Netherlands, and served as a professor at the University of Leiden.
In the 17th century, members of the Rambo family immigrated to North America, settling in Pennsylvania and New Jersey. One of the earliest recorded Rambos in America was Peter Gunnarsson Rambo, who arrived in 1647 from Sweden and established a homestead along the Delaware River.
Another prominent figure was Jacob Rambo, born in 1667 in Tinicum Township, Pennsylvania. He was a prominent landowner and merchant, and his descendants played significant roles in the American Revolutionary War.
Michel Rambo, born in 1692 in Alsace, France, was a Huguenot refugee who fled religious persecution and settled in Pennsylvania in 1710. His descendants became influential figures in the state's early history.
Demographics
Among Census respondents with the surname Rambo, the largest self-reported group is White at 79.4%. The next largest groups are Black (12.8%) and Two or More Races (3.9%).
The bar chart below shows how Rambo 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 Rambo 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.
