Origin
The surname Schlumbrecht has its origins in Germany, tracing back to the late 16th century. It is believed to have originated from the German regions of Bavaria and Baden-Württemberg. The name is derived from the old German words "schlumme" meaning slumber or sleep, and "brecht" which translates to break or crack. This suggests the name may have initially been a descriptive surname referring to someone who was a heavy sleeper or had a tendency to sleep deeply.
One of the earliest recorded instances of the Schlumbrecht name can be found in the church records of the town of Heidelberg, dated 1587. Here, a Johann Schlumbrecht is listed as a resident of the town. In the 17th century, the name appeared in various records across southern Germany, with variations in spelling such as Schlummbrecht and Schlumbercht.
During the 17th and 18th centuries, the Schlumbrecht name became more prevalent in the regions around the Rhine River, particularly in the areas of Palatinate and Alsace. This coincided with a period of migration and resettlement in these regions due to religious conflicts and economic factors.
A notable bearer of the Schlumbrecht name was Hans Schlumbrecht, a merchant and city council member who lived in Strasbourg, Alsace, in the late 16th century. Records indicate he was involved in trade and played a role in local governance.
Another individual of historical significance was Katharina Schlumbrecht, born in 1632 in the town of Gundelsheim, Baden-Württemberg. She was accused of witchcraft during the infamous Würzburg witch trials and was eventually executed in 1629.
In the 19th century, the Schlumbrecht name appeared in various records across Germany and neighboring regions. One notable figure was Friedrich Schlumbrecht, a German-born American engineer and inventor who lived from 1823 to 1902. He is credited with several patents related to textile machinery and manufacturing processes.
Other individuals who bore the Schlumbrecht surname include Johannes Schlumbrecht, a German clockmaker who lived in the late 18th century in the town of Pforzheim, and Margarethe Schlumbrecht, a midwife from the village of Deidesheim in the Palatinate region, who practiced her craft in the early 19th century.
While the origin of the Schlumbrecht name can be traced back to specific regions in Germany, over time it has spread to other parts of Europe and beyond, as families migrated and settled in new areas. Despite its relatively uncommon nature, the name continues to hold a unique place in the history and genealogy of German surnames.
Demographics
Among Census respondents with the surname Schlumbrecht, the largest self-reported group is White at 72.7%. The next largest groups are Hispanic (14.5%) and Black (8.2%).
The bar chart below shows how Schlumbrecht 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 Schlumbrecht 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.
