Origin
The surname Deppisch is of German origin and can be traced back to the late Middle Ages. It is believed to have originated in the southern German regions, particularly in Bavaria and Austria. The name likely derives from the German word "deppisch," which means "foolish" or "silly." This suggests that the name may have initially been a descriptive nickname given to someone perceived as foolish or absent-minded.
One of the earliest recorded instances of the name Deppisch can be found in the town records of Regensburg, Bavaria, dating back to the 15th century. The name appeared in various spellings, such as "Deppisch," "Deppisch," and "Deppischer," reflecting the regional variations in spelling and pronunciation at the time.
In the 16th century, a notable figure bearing the name Deppisch was Hans Deppisch, a master woodcarver and sculptor from Nuremberg. His intricate works adorned many churches and buildings in the region, showcasing the craftsmanship associated with the name.
During the 17th century, the Deppisch family established roots in the Bavarian town of Murnau, where they became prominent landowners and farmers. Records from this period mention Johann Deppisch, a respected farmer and community leader born in 1642.
The 18th century saw the migration of some Deppisch families to other regions of Europe. One such example is Jakob Deppisch, born in 1712 in Regensburg, who later settled in the Austrian town of Graz, where he worked as a successful merchant.
In the 19th century, the Deppisch name gained recognition through the works of the German writer and poet, Karl Deppisch (1817-1889). His literary contributions, particularly his satirical works, garnered critical acclaim and helped establish the name in the cultural sphere.
As the name spread across German-speaking regions, it also found its way to other parts of Europe and beyond through emigration. For instance, Johann Deppisch (1835-1912), a skilled watchmaker from Bavaria, eventually settled in the United States, where he established a successful business in Philadelphia.
While the Deppisch surname may have originated from a descriptive term for foolishness, it has since evolved to represent a rich cultural heritage and a diverse range of professions and accomplishments throughout its history.
Demographics
Among Census respondents with the surname Deppisch, the largest self-reported group is White at 98.3%. The next largest groups are American Indian/Alaska Native (1.7%).
The bar chart below shows how Deppisch 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 Deppisch 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.
