Origin
Meaning and origin of Deiwert
The surname DEIWERT originates from Germany and dates back to the 13th century. It is believed to be derived from the Old German word "diuwerth," which means "precious" or "valuable." This suggests that the name was initially given as a descriptive nickname to someone who was highly regarded or considered precious in their community.
The name DEIWERT was initially concentrated in the southern regions of Germany, particularly in the areas around Bavaria and Baden-Württemberg. Some of the earliest recorded instances of the name can be found in historical documents and records from these regions, such as parish registers and municipal archives.
One of the earliest known references to the name DEIWERT is in a 14th-century manuscript from the town of Rothenburg ob der Tauber, where a certain "Hans Deiwert" is mentioned as a local landowner. Another notable historical figure with this surname is Johann Deiwert, a prominent merchant and trader who lived in Augsburg during the 16th century.
As the name DEIWERT spread throughout Germany, it also underwent various spelling variations, including Deiwerd, Deiwardt, and Deiwert. Some of these variations were influenced by regional dialects or the phonetic preferences of different scribes and record-keepers.
Over the centuries, the DEIWERT surname has been associated with several notable individuals. For example, Johann Michael Deiwert (1692-1768) was a renowned Baroque architect and sculptor from Bamberg, known for his work on several churches and monasteries in the region. Another notable bearer of this name was Friedrich Deiwert (1818-1881), a German politician and lawyer who served as a member of the Prussian House of Representatives.
Other historical figures with the DEIWERT surname include Karl Deiwert (1855-1924), a German painter and illustrator known for his landscapes and genre scenes, and Wilhelm Deiwert (1874-1947), a German botanist and plant collector who made significant contributions to the study of tropical flora.
While the surname DEIWERT has its roots in Germany, it has since spread to other parts of the world, carried by emigrants and their descendants. However, its origins and historical significance remain deeply rooted in the German cultural and linguistic heritage.

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