Origin
The surname MELLENBRUCH is believed to have originated in Germany, with records dating back to the 16th century. It is thought to have derived from the German words "melle" meaning "mill" and "bruch" meaning "stream" or "brook," suggesting it was originally a topographic name referring to a location near a mill stream.
One of the earliest documented references to the name MELLENBRUCH can be found in the Kirchenbücher (church records) of the town of Schmallenberg, located in the region of North Rhine-Westphalia, Germany. These records mention a Johann Mellenbruch, who was born in 1587.
Another early record of the name appears in the Musterungsrollen (muster rolls) of the Thirty Years' War, where a soldier named Hans Mellenbruch is listed as serving in the army of Gustavus Adolphus, the King of Sweden, in 1632.
In the 18th century, the name MELLENBRUCH can be found in various historical documents from the region of Westphalia, such as land records and tax registers. One notable individual from this period was Johann Friedrich Mellenbruch, a merchant and landowner who lived in the town of Soest from 1725 to 1798.
During the 19th century, the MELLENBRUCH name spread beyond Germany as some members of the family immigrated to other parts of Europe and the Americas. One such individual was Carl August Mellenbruch, a German-born engineer who emigrated to Brazil in 1856 and played a significant role in the construction of the country's first railroad.
Another notable figure with the surname MELLENBRUCH was Wilhelm Mellenbruch, a German artist and sculptor who lived from 1838 to 1911. His works were featured in several exhibitions and can be found in museums across Germany.
While the surname MELLENBRUCH is relatively uncommon today, it has a rich history dating back to medieval times and can be traced through various historical records and documents from Germany and beyond.
Demographics

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 Mellenbruch 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.
