Origin
The surname KENIS has its origins in the Middle Ages, originating from the Dutch and German regions of Europe. It is believed to have derived from the Dutch word "kennis," which means "knowledge" or "acquaintance." The name may have been given to someone who was considered knowledgeable or well-connected within their community.
One of the earliest recorded instances of the name KENIS can be found in the historical records of the city of Arnhem, in the Netherlands, dating back to the 14th century. These records mention a man named Jan KENIS, who was a merchant and respected citizen of the city.
In the 15th century, the KENIS name appeared in the records of the city of Cologne, in Germany. Here, a family bearing the name KENIS was known for their expertise in metalworking and were highly regarded for their craftsmanship.
During the 16th century, the name KENIS began to spread across Europe, with records showing individuals bearing this surname in various regions, including France, Belgium, and parts of Eastern Europe.
One notable individual with the KENIS surname was Willem KENIS, a Dutch painter and engraver who lived in the 17th century (1592-1647). His works were highly regarded during his time and can still be found in various art collections across Europe.
In the 18th century, a man named Pieter KENIS (1720-1789) made a significant contribution to the field of architecture. He was a renowned architect from the Netherlands who designed several notable buildings, including the Nieuwe Kerk in Delft.
Another prominent figure with the KENIS surname was Jan KENIS (1815-1892), a Belgian poet and writer who gained recognition for his works celebrating the Flemish language and culture.
The 19th century also saw the rise of a French military officer named Jacques KENIS (1832-1905), who served with distinction in the Franco-Prussian War and was awarded the Légion d'Honneur for his bravery.
As the KENIS name spread across different regions, it underwent various spelling variations, such as KENNIS, KENIUS, and KENNYS, reflecting local dialects and language influences.
Demographics
Among Census respondents with the surname Kenis, the largest self-reported group is White at 88.1%. The next largest groups are Hispanic (9.2%) and Black (2.8%).
The bar chart below shows how Kenis 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 Kenis 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.
