Origin
The surname WARMBROD originated in Germany during the late medieval period, likely between the 13th and 15th centuries. It is derived from the Old German words "warm" meaning warm or hot, and "brod" meaning bread, suggesting an occupational origin related to baking or working with ovens.
One of the earliest recorded instances of the WARMBROD name can be found in the Kirchenbücher (church records) of the town of Rothenburg ob der Tauber in Bavaria, dating back to the early 16th century. These records mention a family by the name of Warmbrod residing in the area.
In the late 16th century, the WARMBROD name appeared in various legal documents and property records in the region of Franconia, which was part of the Holy Roman Empire at the time. This suggests that the family had established itself and was involved in various trades and professions.
During the 17th and 18th centuries, several notable individuals with the WARMBROD surname emerged. One such person was Johann Warmbrod (1642-1701), a German theologian and author who served as a pastor in the city of Nuremberg and wrote several religious texts.
Another figure of note was Christoph Warmbrod (1719-1787), a German architect and builder who was responsible for the construction of several churches and public buildings in the region of Thuringia.
In the 19th century, the WARMBROD name continued to appear in various records, including birth, marriage, and death registers across different parts of Germany. One prominent individual from this period was August Warmbrod (1825-1892), a German politician and lawyer who served as a member of the Reichstag (German parliament) representing the city of Kassel.
As the 20th century dawned, the WARMBROD surname spread beyond Germany due to emigration and global mobility. One notable figure was Hans Warmbrod (1903-1989), a German-American engineer and inventor who played a significant role in the development of early rocket technology during World War II.
Throughout its history, the WARMBROD surname has maintained its German roots and has been carried by individuals from various walks of life, including bakers, artisans, clergy, architects, politicians, and scientists, among others.
Demographics
Among Census respondents with the surname Warmbrod, the largest self-reported group is White at 94.5%. The next largest groups are Black (2.8%) and Hispanic (2.8%).
The bar chart below shows how Warmbrod 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 Warmbrod surname at the time of the 2020 Census, not any inherent property of the name itself.
