Origin
Meaning and origin of Koxlien
The surname KOXLIEN is believed to have originated in the northern regions of Germany and Denmark during the late 15th century. It is derived from the Old German word "koxe," meaning "coachman" or "one who drives a carriage." The name likely evolved from an occupational surname given to individuals whose primary trade involved transporting people or goods by horse-drawn carriage.
One of the earliest documented references to the KOXLIEN surname can be found in a 16th-century census record from the town of Schleswig, which was part of the Duchy of Schleswig at the time. The record lists a family headed by Hans KOXLIEN, a coachman employed by a local nobleman.
In the 17th century, the KOXLIEN name began to appear in various church records and municipal documents across northern Germany and southern Denmark. Notable individuals from this period include Jürgen KOXLIEN (1632-1701), a respected coachman who served the Duke of Mecklenburg-Schwerin, and Anna KOXLIEN (1649-1723), a midwife renowned for her skills in the town of Lübeck.
As the KOXLIEN name spread throughout the region, it underwent various spelling variations, such as KOXLIN, KOXLEN, and KOXLIEN. These variations were often influenced by local dialects and scribes' interpretations.
During the 19th century, several members of the KOXLIEN family achieved prominence in their respective fields. Johann KOXLIEN (1812-1887) was a master carriage builder whose intricate designs were highly sought after by wealthy patrons across Europe. His son, Friedrich KOXLIEN (1845-1921), followed in his footsteps and became a renowned coachman, serving in the royal court of Denmark.
Another notable figure from this era was Wilhelmina KOXLIEN (1829-1901), a pioneering educator who established one of the first schools for girls in the city of Hamburg. Her efforts paved the way for greater educational opportunities for women in northern Germany.
While the KOXLIEN surname has its roots in an occupational lineage, it has since become a respected family name carried by individuals from diverse backgrounds and professions. Despite its relatively modest origins, the name has endured through centuries, reflecting the rich cultural heritage of northern Germany and Denmark.

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

Does the Census include every surname?

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