Origin
Meaning and origin of Koglin
The surname KOGLIN is of German origin, derived from the Old German words "kogel" and "lin," which together roughly translate to "little knoll" or "small hill." It is believed to have originated in the region of Lower Saxony, Germany, during the late Middle Ages, around the 13th or 14th century.
One of the earliest recorded instances of the surname KOGLIN can be found in the Hanseatic League's merchant records from the city of Lübeck, dating back to the late 15th century. These records mention a trader named Hans KOGLIN, who dealt in textiles and spices imported from the Netherlands and Italy.
The name KOGLIN is also found in various church records from the 16th and 17th centuries, primarily in the regions of Mecklenburg and Pomerania in northern Germany. One notable example is Johann KOGLIN, a Protestant minister who was born in Rostock in 1575 and served as a pastor in Greifswald until his death in 1642.
During the 18th century, the surname KOGLIN began to spread further throughout Germany and neighboring countries. In 1712, a man named Christian KOGLIN was recorded as a resident of the town of Zittau, located in present-day eastern Germany, near the border with Poland and the Czech Republic.
In the 19th century, the name KOGLIN gained some prominence in the field of education. Karl Friedrich KOGLIN, born in Berlin in 1811, was a renowned educator and author of several textbooks on mathematics and science. He taught at various schools in Berlin and later became the director of the Luisenstädtische Realschule, a prestigious secondary school in the city.
Another notable figure with the surname KOGLIN was Otto KOGLIN, a German architect and urban planner who lived from 1865 to 1942. He was responsible for designing several important buildings and public spaces in Berlin, including the Märkisches Museum and the Charlottenburg Palace gardens.
While the surname KOGLIN is most commonly associated with Germany, it has also been found in other parts of Europe and beyond, likely due to migration patterns over the centuries. However, the name's roots can be traced back to the German regions of Lower Saxony and northern Germany, where it originated from the Old German words describing a small hill or knoll.

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

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
