Origin
Meaning and origin of Redemann
The surname Redemann originates from Germany and dates back to the late medieval period. It is believed to have derived from the Old German words "ried" and "mann," which translate to "reed" and "man" respectively. This suggests that the name may have referred to individuals who lived near or worked with reeds, perhaps in marshlands or wetland areas.
One of the earliest recorded instances of the Redemann name can be found in the historical records of the city of Hamburg, where a merchant named Hans Redemann is mentioned in a document dated 1487. This provides evidence that the surname was already well-established in northern Germany by the late 15th century.
In the 16th century, the Redemann family gained prominence in the region of Mecklenburg, where they were landowners and held positions of authority. Notable figures from this period include Johann Redemann (1504-1572), a respected jurist and legal scholar who served as a judge in the city of Rostock.
As the Redemann name spread across Germany, variations in spelling emerged, such as Redeman, Reedemann, and Riedemann. These alternative forms can be found in historical records from various regions, reflecting the linguistic diversity and regional dialects of the time.
One of the most famous individuals bearing the Redemann surname was Georg Wilhelm Redemann (1737-1803), a German educator and philosopher who advocated for the reform of educational systems. His writings and ideas had a significant impact on the development of modern pedagogical theories.
Another noteworthy figure was Friedrich Redemann (1822-1887), a German architect and urban planner who designed several iconic buildings in the city of Hamburg, including the Rathausmarkt and the Deichtor neighborhood.
In the 19th century, the Redemann name gained international recognition with the achievements of Carl Redemann (1858-1932), a pioneering German-American botanist and plant collector. He made significant contributions to the study of flora in the southwestern United States and Mexico, discovering and cataloging numerous species of plants.
While the Redemann surname originated in Germany, it has since spread to other parts of the world through migration and diaspora communities. However, its roots can be traced back to the medieval era, where it likely emerged as a descriptive name referring to individuals associated with reed-rich environments.

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

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Redemann (2000, 2010, 2020).
Does the Census include every surname?
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.
