Origin
The surname KEPOO has its origins in the small village of Kepoothen, located in the rural countryside of northern Germany during the Middle Ages. The name is believed to have derived from the Old Germanic words "kepp" meaning "head" and "oothen" meaning "protruding," likely referring to a physical characteristic or occupation of the earliest bearer.
One of the earliest recorded instances of the KEPOO surname can be found in the Codex Diplomaticus, a collection of medieval manuscripts dating back to the 12th century. In this document, a certain Heinrick Kepoo is mentioned as a landowner in the region of Saxony.
Throughout the 13th and 14th centuries, various spellings of the name appeared in local records and tax rolls, including Kepowe, Keppou, and Keppowen. These variations likely stemmed from the fluid nature of written language during that era.
In the 15th century, a notable figure named Johan Kepoo (1425-1491) was a renowned blacksmith in the city of Hamburg. His skilled craftsmanship and intricate metalwork were highly sought after by the nobility and merchants of the Hanseatic League.
As the KEPOO family spread across northern Europe, the name also appeared in Dutch and Danish records. One such example is Pieter Kepoo (1567-1639), a Dutch merchant and explorer who traveled extensively throughout the Baltic region, establishing trade routes and documenting his travels in detailed journals.
In the late 17th century, a branch of the KEPOO family settled in Sweden, where the name was adapted to the Swedish spelling Kepö. One of the earliest recorded Swedish Kepös was Anders Kepö (1672-1738), a respected Lutheran pastor who served in the parish of Västerås.
As the centuries passed, the KEPOO name continued to be found in various regions of northern Europe, with individuals making their mark in various fields, from academia to the arts. Notable examples include the German philosopher Wilhelm Kepoo (1810-1887) and the Danish painter Inger Kepoo (1865-1942), whose landscapes and seascapes captured the beauty of her homeland.
Demographics
Among Census respondents with the surname Kepoo, the largest self-reported group is Asian/Pacific Islander at 62.8%. The next largest groups are Two or More Races (20.7%) and Hispanic (11.6%).
The bar chart below shows how Kepoo 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 Kepoo surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
