Origin
The surname Rehorn has its origins in Germany, emerging during the medieval period around the 12th century. It is believed to be derived from the Old German words "reho" meaning "deer" and "horn," suggesting a connection to the trade or occupation of hunting deer or crafting deer horn products.
One of the earliest recorded instances of the surname Rehorn can be found in the 14th-century German manuscript known as the "Codex Diplomaticus Saxoniae Regiae," which chronicles land transactions and legal matters in the region of Saxony. This document mentions individuals with the surname Rehorn residing in the town of Wittenberg.
During the 15th century, a notable figure with the surname Rehorn was Hans Rehorn, a skilled craftsman renowned for his intricate carvings of deer antlers. His works adorned many noble households across central Europe, and his name is mentioned in the records of several prestigious guilds in Nuremberg and Augsburg.
In the 16th century, the Rehorn surname gained prominence in the northern German regions, particularly in the city of Hamburg. Johannes Rehorn (1490-1568), a merchant and shipowner, is credited with establishing one of the earliest trading companies that facilitated the import of exotic goods from the Dutch East Indies.
As the centuries progressed, the Rehorn surname continued to spread across various regions of Germany and beyond. In the 18th century, a prominent military figure named Friedrich Wilhelm Rehorn (1712-1781) served as a captain in the Prussian army under King Frederick the Great, earning recognition for his valor during the Seven Years' War.
Another notable individual with the surname Rehorn was Katharina Rehorn (1805-1879), a celebrated German novelist and poet. Her works, which often explored themes of love, nature, and the human condition, gained widespread popularity during the Romantic period and continue to be studied in literary circles.
Over time, the Rehorn surname has undergone various spelling variations, such as Rehhorn, Reehorne, and Raehorn, reflecting regional linguistic differences and adaptations. While the name may have originated in connection with deer hunting or antler crafting, it has since evolved to represent a rich tapestry of German heritage and cultural influences.
Demographics
Among Census respondents with the surname Rehorn, the largest self-reported group is White at 82.6%. The next largest groups are Two or More Races (7.3%) and Hispanic (6.4%).
The bar chart below shows how Rehorn 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 Rehorn surname at the time of the 2020 Census, not any inherent property of the name itself.
