Origin
The surname "GANSMAN" is thought to have originated in Germany, with its earliest recorded use dating back to the 13th century. The name is believed to be derived from the Old German word "gansman," which referred to a person who oversaw or managed a group of people or workers, such as a foreman or overseer.
In its early years, the name was primarily found in the regions of Bavaria and Saxony, where it was associated with individuals who held positions of authority within various trades and professions. The spelling of the name has remained relatively consistent over time, with minor variations such as "Gansman," "Ganssmann," and "Gansmann" appearing in historical records.
One of the earliest known references to the name can be found in a 14th-century manuscript from the city of Nuremberg, which mentions a "Hans Gansman" who was a prominent merchant and guild member. Another notable figure bearing this surname was Johann Gansman (1492-1551), a German theologian and professor at the University of Wittenberg, who was a contemporary of Martin Luther and played a role in the Protestant Reformation.
During the 16th and 17th centuries, the name began to spread beyond Germany to other parts of Europe as individuals with this surname migrated or emigrated. For instance, in the Netherlands, there are records of a family named "Gansman" residing in Amsterdam in the late 16th century, while in England, the name can be traced back to the early 17th century, likely brought by German immigrants.
Other notable individuals with the surname "Gansman" include:
1. Franz Gansman (1760-1828), a German composer and music teacher from Saxony.
2. Heinrich Gansman (1795-1865), a German painter and engraver from Berlin.
3. Wilhelmine Gansman (1807-1882), a German actress and opera singer who performed in several major European cities.
4. August Gansman (1824-1902), a German-American engineer and inventor who designed and patented various agricultural machines and tools.
5. Karl Gansman (1876-1941), a German architect and urban planner who contributed to the development of several German cities in the early 20th century.
While the surname "Gansman" is not among the most common surnames globally, it has a rich history and can be traced back to its origins in medieval Germany, where it was associated with individuals in positions of authority and management within various professions and trades.
Demographics
Among Census respondents with the surname Gansman, the largest self-reported group is White at 100.0%.
The bar chart below shows how Gansman 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 Gansman 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.
