Origin
Meaning and origin of Schromm
The surname Schromm is of German origin, with its roots tracing back to the late medieval period in the region of modern-day Bavaria. It is believed to be derived from the Middle High German word "schrump," which referred to a wrinkle or crease, potentially indicating an early descriptive nickname for someone with a wrinkled or creased appearance.
One of the earliest recorded instances of the Schromm surname appears in the Codex Diplomaticus Brandenburgensis, a collection of historical documents from the Margraviate of Brandenburg, dating back to the 14th century. In this codex, there is a reference to a certain "Johannes Schromm" from the town of Neuruppin.
During the Renaissance period, the Schromm family seemed to have established a presence in the city of Nuremberg, with records from the 16th century mentioning a merchant named Hans Schromm (1510-1587), who was involved in the thriving textile trade of the time.
In the 17th century, a notable figure bearing the Schromm surname was Johann Schromm (1625-1693), a Lutheran theologian and author from Saxony. His writings on religious doctrine and biblical exegesis were widely circulated during the era of the Protestant Reformation.
The 18th century saw the emergence of Johann Christoph Schromm (1739-1812), a German composer and organist from Württemberg. His works, including numerous church cantatas and organ pieces, were influential in the development of sacred music during the late Baroque and early Classical periods.
In the 19th century, the Schromm name gained prominence in the field of geology, with Karl von Schromm (1815-1889), a German geologist and paleontologist who made significant contributions to the study of fossils and stratigraphic formations in the Alps.
Another notable figure from this era was Wilhelm Schromm (1846-1923), a German architect and urban planner. He was responsible for the design and construction of several iconic buildings and public spaces in cities such as Berlin and Dresden.
As the Schromm surname spread across different regions of Germany and neighboring countries, it also adopted various slight variations in spelling, including Schrom, Schroem, and Schroem, reflecting local dialects and orthographic preferences.

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 Schromm surname at the time of the 2020 Census, not any inherent property of the name itself.
