Origin
Meaning and origin of Darm
The surname DARM is believed to have originated in Germany during the medieval period. It likely derived from the Old High German word "darm," meaning "intestine" or "gut." This suggests that the name may have been an occupational surname referring to someone who worked as a butcher or in the meat trade.
One of the earliest recorded instances of the name DARM can be found in the tax records of the town of Cologne in 1312, where a certain Johannes Darm is listed as a resident. The name also appears in various medieval documents and records from other parts of Germany, such as the Würzburg census of 1397, which mentions a Konrad Darm.
In the 15th century, the DARM surname spread to other regions of Europe. For example, a merchant named Hans Darm is recorded as living in the city of Vienna, Austria, in 1457. Around the same time, a family named Darm settled in the Swiss canton of Bern, where they became prominent citizens.
One notable figure in the history of the DARM surname is Johann Darm, a German Lutheran theologian and reformer who lived from 1500 to 1572. He was a close associate of Martin Luther and played a significant role in the Protestant Reformation.
Another individual of note is Catharina Darm, a German-born woman who immigrated to the British colony of Pennsylvania in the early 18th century. She is recorded as having married Johannes Schaeffer in 1712 in the city of Philadelphia.
In the 19th century, the DARM surname can be found among German immigrants to the United States. For instance, a man named Friedrich Darm settled in the town of Watertown, Wisconsin, in 1847, where he worked as a farmer.
While the DARM name has its roots in Germany, it has since spread to various parts of the world due to migration and immigration. However, it remains a relatively uncommon surname, particularly outside of German-speaking regions.

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