Origin
Meaning and origin of Adermann
The surname Adermann is of German origin, with its roots dating back to the medieval period. It is believed to have originated as a locational name, derived from the place name "Adermannstein" or "Adermannsweiler," both of which are small villages located in the southwestern region of Germany.
The name Adermann is thought to be a compound word, consisting of two parts: "Ader" and "Mann." The prefix "Ader" is an old German word meaning "vein" or "watercourse," while "Mann" translates to "man." This suggests that the name may have initially referred to someone who lived near a vein or small stream.
One of the earliest recorded instances of the name Adermann can be found in the Liber Censuum, a medieval manuscript compiled in the 13th century, which lists a certain "Conradus Adermann" from the town of Worms, located in the modern-day state of Rhineland-Palatinate, Germany.
In the 16th century, the name appears in the records of the city of Nuremberg, where a prominent merchant and councilor named Hans Adermann (1510-1578) played a significant role in the city's affairs. Another noteworthy figure was Johann Adermann (1592-1667), a German theologian and professor of theology at the University of Wittenberg.
In the 17th century, a line of the Adermann family settled in the town of Wolfenbüttel, in the Duchy of Brunswick-Lüneburg (now part of Lower Saxony, Germany). Here, the name is recorded in various church and municipal records, with individuals such as Christian Adermann (1621-1684), a respected magistrate, and his son, Johann Friedrich Adermann (1651-1718), a renowned painter and engraver.
Moving into the 18th century, the Adermann name gained prominence in the field of music with the birth of Johann Walther Adermann (1720-1786), a German composer and organist who served as the court Kapellmeister in the city of Celle, in the Electorate of Hanover.
Another notable figure bearing the Adermann surname was Karl Friedrich Adermann (1770-1842), a German jurist and legal scholar who served as a professor of law at the University of Göttingen and contributed significantly to the development of German civil law.

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