Origin
The surname KROBATH has its origins in Germany, with records of the name dating back to the 17th century. The name is believed to have derived from the German word "Krobat," which referred to a person from Croatia. This suggests that the earliest bearers of the name may have been immigrants or descendants of immigrants from the region of Croatia.
One of the earliest recorded instances of the KROBATH surname can be found in the baptismal records of the town of Regensburg, Bavaria, in 1652. The entry mentions a child named Johannes KROBATH, son of Matthias KROBATH and his wife Anna. This suggests that the family had already been established in the region for some time.
In the late 18th century, a man named Johann KROBATH (1765-1847) is recorded as having been a prominent merchant and landowner in the town of Neustadt an der Waldnaab, located in the Upper Palatinate region of Bavaria. His success in business and landholdings likely contributed to the spread and recognition of the KROBATH name in the area.
Historical records from the 19th century indicate that the KROBATH surname had spread to other parts of Germany, as well as to neighboring countries. For example, in 1856, a man named Friedrich KROBATH (1823-1887) was born in the town of Sławięcice, which was then part of Prussia (now located in modern-day Poland).
One notable figure with the KROBATH surname was Karl KROBATH (1898-1967), an Austrian politician and lawyer who served as the Minister of Finance of Austria from 1945 to 1949. His tenure played a crucial role in the economic recovery of Austria in the aftermath of World War II.
Another individual of historical significance was Wilhelm KROBATH (1909-1984), a German physicist and engineer who made significant contributions to the development of radar technology during World War II. His work had a lasting impact on the field of electronics and communication systems.
While the KROBATH surname may have originated as a reference to Croatian heritage, it has since become well-established in various parts of Germany, Austria, and other regions of Central and Eastern Europe, with each generation contributing to the rich tapestry of its history and significance.
Demographics
Among Census respondents with the surname Krobath, the largest self-reported group is White at 95.5%. The next largest groups are Hispanic (4.5%).
The bar chart below shows how Krobath 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 Krobath surname at the time of the 2020 Census, not any inherent property of the name itself.
