Origin
Meaning and origin of Reohr
The surname REOHR is of German origin, with roots dating back to the early 16th century. The name is believed to have originated from the region of Saxony, where it was likely derived from the Old German word "rōr," meaning "reed" or "cane." This connection suggests that the earliest bearers of the name may have resided near areas with abundant reeds or marshlands.
One of the earliest recorded instances of the name can be found in the parish records of the town of Merseburg, where a certain Hans Reohr was listed as a resident in 1538. This entry provides insight into the name's geographical distribution during the Renaissance period.
In the 17th century, the REOHR surname appeared in various historical documents across central Germany. Notable mentions include Johann Reohr, a merchant from Leipzig who was documented in 1625, and Elise Reohr, a midwife from Erfurt whose name appears in a local registry from 1678.
As the centuries progressed, the REOHR name spread throughout the German-speaking regions of Europe. In the late 18th century, a prominent figure bearing this surname was Friedrich Reohr (1734-1804), a respected theologian and author from Nuremberg.
Another notable individual was Gottfried Reohr (1812-1891), a German-born artist who immigrated to the United States and became renowned for his landscape paintings depicting the American West. His works are part of the permanent collections of several museums, including the Metropolitan Museum of Art in New York.
In the 20th century, the REOHR name gained recognition through the achievements of Hans Reohr (1908-1987), a German engineer and inventor who held numerous patents for his innovative work in the field of automotive technology.
While the REOHR surname may have evolved in spelling and pronunciation over the centuries, its origins can be traced back to the marshlands of central Germany, where the earliest bearers of this name likely resided and derived their livelihood from the abundant reeds and canes surrounding their communities.

The bar chart below shows how Reohr 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 Reohr surname at the time of the 2020 Census, not any inherent property of the name itself.
