Origin
Meaning and origin of Treubig
The surname TREUBIG has its origins in Germany, emerging in the late 15th century. It is believed to derive from the German word "treu," meaning loyal or faithful, combined with the suffix "-big," indicating a person or place. This suggests the name may have initially referred to someone from a location associated with loyalty or allegiance.
One of the earliest recorded instances of the TREUBIG name appears in a 1492 document from the town of Quedlinburg in Saxony-Anhalt, Germany. The document mentions a farmer named Hans TREUBIG who owned land in the region. Another early reference is found in the 1506 parish records of the town of Zerbst, where a blacksmith named Peter TREUBIG is listed.
In the 16th century, the TREUBIG name spread to other parts of Germany, with records showing families in Bavaria, Thuringia, and Brandenburg. Notable individuals from this period include Johann TREUBIG (1524-1586), a Lutheran theologian and professor at the University of Wittenberg, and Anna TREUBIG (1557-1628), a prominent member of the Lutheran church in Nuremberg.
During the 17th and 18th centuries, the TREUBIG name continued to be found across various German regions. In 1673, a man named Wilhelm TREUBIG is recorded as a merchant in the city of Hamburg. In 1712, the birth of Christoph TREUBIG is registered in the town of Erfurt, and he later became a respected clockmaker in the region.
One of the most prominent figures with the TREUBIG surname was Friedrich TREUBIG (1781-1855), a German philosopher and professor at the University of Leipzig. His works on ethics and moral philosophy were widely influential during the 19th century.
As the 19th century progressed, the TREUBIG name began to appear in other parts of Europe and beyond, likely due to emigration from Germany. For example, there are records of a TREUBIG family settling in the United States in the mid-1800s, with Johann TREUBIG (1820-1897) establishing a successful farming community in Ohio.

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 Treubig 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.
