Origin
The surname Rohmer is of German origin, originating from the medieval German word "Rohmer," which means "one who comes from Rome." This name was likely given to individuals who had traveled to or lived in Rome during the Middle Ages.
The earliest recorded use of the name Rohmer can be traced back to the 13th century in the region of Bavaria, Germany. It is believed that the name first appeared in the town of Rohr, which is located in the district of Regen, Bavaria. The town's name is derived from the German word "Rohr," meaning "reed" or "cane," suggesting that the area may have been known for its abundance of reeds or cane plants.
In the 14th century, the name Rohmer appeared in various records and manuscripts throughout Germany, including the Codex Diplomaticus Brandenburgensis, a collection of historical documents from the region of Brandenburg. This suggests that the name had spread beyond Bavaria and was becoming more widespread.
One of the earliest recorded individuals with the surname Rohmer was Johannes Rohmer, a German monk who lived in the 15th century. He was known for his writings on theology and philosophy, and his works were widely circulated throughout Europe.
In the 16th century, the name Rohmer gained prominence with the birth of Christoph Rohmer (1500-1568), a German Protestant reformer and theologian. He was a close associate of Martin Luther and played a significant role in the Protestant Reformation.
Another notable individual with the surname Rohmer was Johann Rohmer (1630-1698), a German composer and organist. He was known for his sacred music and was highly regarded in his time.
During the 17th century, the name Rohmer also appeared in various places across Europe, such as the Netherlands and Switzerland, indicating that individuals with this surname had migrated from Germany to other regions.
In the 18th century, Friedrich Rohmer (1720-1790) was a German philosopher and writer who contributed to the Enlightenment movement. His works focused on rationalism and the pursuit of knowledge.
As the centuries passed, the surname Rohmer continued to be found throughout Germany and other parts of Europe, with individuals bearing this name making contributions in various fields, including literature, science, and the arts.
Demographics
Among Census respondents with the surname Rohmer, the largest self-reported group is White at 87.5%. The next largest groups are Hispanic (7.0%) and Asian/Pacific Islander (2.8%).
The bar chart below shows how Rohmer 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 Rohmer 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.
