Origin
The surname Colhoff is of German origin, first appearing in records dating back to the 16th century. It is believed to have originated in the town of Kolbenhoff, located in the northern region of Germany, near the border with Denmark. The name is derived from the Old German words 'kolt' meaning 'charcoal' and 'hoff' meaning 'dwelling' or 'courtyard', suggesting that the earliest bearers of this name were likely charcoal burners or lived in an area associated with charcoal production.
One of the earliest recorded instances of the Colhoff surname can be found in the parish records of St. Peter's Church in Kolbenhoff, where a man named Hans Colhoff was listed as a tenant farmer in 1532. Another early reference is found in the Prussian military records from the late 16th century, where a soldier named Christoph Colhoff is mentioned as serving in the army of the Elector of Brandenburg.
During the 17th and 18th centuries, the Colhoff name began to spread beyond its original region as families migrated to other parts of Germany and neighboring countries. Notable individuals bearing this surname include Johann Colhoff (1612-1688), a renowned clockmaker from Nuremberg, and Katharina Colhoff (1738-1805), a midwife from the town of Mertendorf, who was recognized for her exceptional service to the community.
As the Industrial Revolution took hold in Europe, many Colhoffs left their rural homeland seeking new opportunities in urban areas. One such individual was Wilhelm Colhoff (1822-1899), a successful businessman and entrepreneur who established a thriving textile factory in Berlin. His son, Friedrich Colhoff (1854-1928), went on to become a prominent architect and designed several notable buildings in the city.
In the late 19th and early 20th centuries, members of the Colhoff family also emigrated to other parts of the world, including North America and Australia. One notable figure was Hans Colhoff (1876-1945), a German-born engineer who played a significant role in the construction of the Panama Canal before settling in New York City.
Throughout its history, the Colhoff surname has maintained a strong presence in various regions of Germany, with many families continuing to reside in the areas where the name first originated. While the name may have evolved slightly in its spelling over the centuries, its roots can be traced back to the charcoal-burning communities of northern Germany in the medieval era.
Demographics
Among Census respondents with the surname Colhoff, the largest self-reported group is American Indian/Alaska Native at 41.1%. The next largest groups are Two or More Races (29.0%) and White (21.5%).
The bar chart below shows how Colhoff 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 Colhoff surname at the time of the 2020 Census, not any inherent property of the name itself.
