Origin
Meaning and origin of Notbohm
The surname NOTBOHM has its origins in the northern Germanic regions of Europe, likely originating in the late medieval period around the 13th or 14th century. It is believed to have derived from a combination of the Old Norse words "not" meaning "nut" and "bohm" meaning "tree" or "wood", suggesting a connection to a prominent nut tree or wooded area where the earliest bearers of the name may have lived or worked.
One of the earliest recorded instances of the NOTBOHM name can be found in a 15th-century German land registry, indicating the presence of a family with this surname in the region now known as Lower Saxony. The spelling at the time was slightly different, appearing as "Notbohm" or "Notbohme".
In the 16th century, a notable figure named Hans NOTBOHM (1522-1590) was a respected merchant and alderman in the Hanseatic city of Lübeck, located in present-day northern Germany. His prominence in the city's mercantile affairs may have contributed to the further spread and recognition of the NOTBOHM surname.
During the 17th century, a branch of the NOTBOHM family migrated to the Netherlands, where the name was recorded in various municipal records of Amsterdam and other Dutch cities. One such individual was Jan NOTBOHM (1645-1712), a prosperous shipowner and trader who played a role in the city's maritime commerce.
As the centuries progressed, the NOTBOHM name continued to spread across Europe, with records indicating bearers in regions such as Scandinavia, the Baltic states, and even as far as Russia. A notable Russian NOTBOHM was Andrei NOTBOHM (1781-1854), a military officer who served in the Imperial Russian Army during the Napoleonic Wars.
In the 19th century, several NOTBOHM individuals made their mark in various fields. Heinrich NOTBOHM (1822-1897) was a German jurist and legal scholar who contributed significantly to the development of commercial law. Meanwhile, Karl NOTBOHM (1841-1908) was a renowned architect and urban planner in Hamburg, responsible for designing several iconic buildings and urban spaces in the city.
While the NOTBOHM surname is relatively uncommon globally, it has maintained a presence throughout its regions of origin, particularly in northern Germany and the surrounding areas. The name's enduring legacy serves as a testament to the rich cultural and historical tapestry woven by the diverse surnames of Europe.

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