Origin
The surname Umbach originated in the region of Germany, specifically in the areas around the Rhine and Mosel rivers. The name dates back to the early Middle Ages, around the 9th or 10th century. It is derived from the Old High German words "um" meaning "near" and "bach" meaning "stream" or "brook." This suggests that the name was initially given to someone who lived near a small stream or brook.
One of the earliest recorded references to the name Umbach can be found in the Codex Diplomaticus, a collection of historical documents from the German state of Hesse, dating back to the 12th century. The name appears in various spellings, such as Umbach, Umbach, and Ummbach, reflecting the regional variations in pronunciation and spelling at the time.
In the 13th century, the name Umbach appears in the records of the town of Andernach, located on the Rhine River. This suggests that the name was well-established in the region by this time. The town of Umbach, located in the Palatinate region of Germany, likely took its name from the surname, further indicating the name's deep roots in the area.
One notable individual with the Umbach surname was Johann Umbach, a German printer and publisher who lived in the late 15th and early 16th centuries. He is credited with printing several important works, including the first edition of the Hortus Sanitatis, an influential early printed book on natural history and medicine.
Another historical figure with the Umbach surname was Kaspar Umbach, a German composer and organist who lived in the 16th century. He was active in the court of the Palatinate and is known for his compositions for organ and choral works.
In the 18th century, Johann Georg Umbach (1718-1786) was a notable German architect and sculptor. He was responsible for the design and construction of several significant buildings, including the Church of St. Peter and Paul in Jüchen, which is considered a masterpiece of Baroque architecture in the region.
The Umbach surname also has a presence in other parts of Europe, including Switzerland and Austria. One notable Swiss bearer of the name was Johann Jakob Umbach (1799-1867), a politician and historian who served as the President of the Swiss Federal Council in 1848.
In the 19th century, Carl Umbach (1839-1906) was a German-American artist and illustrator. He is best known for his illustrations in Harper's Magazine and his depictions of everyday life in America during the late 19th century.
Demographics
Among Census respondents with the surname Umbach, the largest self-reported group is White at 93.3%. The next largest groups are Two or More Races (2.8%) and Asian/Pacific Islander (1.7%).
The bar chart below shows how Umbach 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 Umbach 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.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
