Origin
The surname SPRUCK is thought to have originated in the region of Saxony in present-day Germany during the Middle Ages. It is believed to be derived from the Old High German word "sprok," which meant a branch or twig, suggesting that the name may have referred to someone who lived near a wooded area or who worked with wood.
One of the earliest recorded instances of the SPRUCK surname appears in the Codex Diplomaticus Saxoniae, a collection of medieval documents from Saxony, dating back to the 12th century. The name is listed as "Sproc" in a document from 1192, which mentions a landowner named Berthold Sproc.
In the 13th century, the name appears in various forms, such as "Sprocke" and "Sprok," in the records of the city of Magdeburg, indicating that the family had established itself in the area. A notable figure from this time was Konrad Sprock, a merchant and alderman in Magdeburg who lived during the late 1200s.
The SPRUCK surname can also be traced to the town of Sprockhovel, located in the Ruhr region of Germany. The town's name, which dates back to the 13th century, is derived from the same Old High German root as the surname, suggesting a connection between the place and the family name.
In the 16th century, a prominent figure bearing the SPRUCK surname was Johann Spruck, a Lutheran theologian and reformer who lived from 1505 to 1567. He was a close associate of Martin Luther and played a significant role in the Protestant Reformation.
Another notable individual with the SPRUCK surname was Christoph Spruck, a German composer and organist who lived from 1610 to 1675. He was highly regarded during his lifetime and composed numerous works for organ and choir.
As the SPRUCK family migrated and spread across Europe, the name underwent various spelling variations, including Sprok, Spruk, and Sprück. In the 19th century, Johann Gottlieb Sprück, a German-born farmer and settler, brought the SPRUCK name to the United States when he immigrated to Wisconsin in 1848.
Demographics
Among Census respondents with the surname Spruck, the largest self-reported group is White at 98.0%. The next largest groups are Hispanic (1.0%) and Asian/Pacific Islander (1.0%).
The bar chart below shows how Spruck 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 Spruck 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.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
