Origin
Meaning and origin of Kondrath
The surname KONDRATH is believed to have originated in the region of Schleswig-Holstein, a state in northern Germany, around the 16th century. It is derived from the Old Germanic words "kund" meaning "known" or "famous" and "rath" meaning "counsel" or "advice." The combination suggests the name may have been associated with a respected counselor or advisor.
The earliest recorded instances of the name KONDRATH can be traced back to parish records and tax rolls from the late 1500s in the towns of Kiel and Lübeck in Schleswig-Holstein. Variations in spelling during that time included Konderath, Kondradt, and Kundrath.
In the 17th century, a notable bearer of the name was Johann Kondrath, a Lutheran theologian and rector of the Gymnasium Illustre in Gotha, Germany, who lived from 1592 to 1657. His published works include treatises on religious philosophy and commentaries on biblical texts.
During the 18th century, the KONDRATH name appears in military records from the Prussian and Hanoverian armies, indicating that members of the family served as soldiers or officers. One such individual was Heinrich Kondrath, a Prussian officer who fought in the Seven Years' War from 1756 to 1763.
In the 19th century, a prominent figure with the KONDRATH surname was Karl Kondrath, a German engineer and industrialist born in 1824 in Lübeck. He is credited with significant advancements in the development of steam engines and the establishment of several successful manufacturing companies.
Another notable bearer of the KONDRATH name was Emilie Kondrath, a German painter and illustrator born in 1857 in Hamburg. Her works, which often depicted scenes of everyday life and landscapes, were exhibited in various galleries across Europe during the late 19th and early 20th centuries.
Throughout its history, the KONDRATH surname has maintained strong roots in northern Germany, particularly in the states of Schleswig-Holstein, Lower Saxony, and Hamburg. While it may have spread to other regions over time, the name's origins and earliest recorded instances can be traced back to the area around the Baltic Sea coast.

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