Origin
Meaning and origin of Kenski
The surname Kenski is of Polish origin, and it can be traced back to the 14th century. Originally, the name was derived from the Polish word "kensk," which meant "a woman's dress." It is believed that the name was initially used as a descriptive name for someone who worked with or sold women's clothing.
The earliest recorded mention of the name Kenski can be found in a document from the town of Krakow, dated 1387. This document references a person named Jan Kenski, who was a tailor by trade. The name also appears in several other historical records from the region, including tax records and church registers.
During the 16th century, the name Kenski began to spread to other parts of Poland, as well as to neighboring countries such as Ukraine and Belarus. It is possible that some variations of the spelling, such as Kensky or Kenski, emerged during this period.
One notable individual with the surname Kenski was Tomasz Kenski, born in 1602 in the village of Brzesko, near Krakow. Tomasz was a renowned poet and playwright, and his works were widely acclaimed during his lifetime.
In the 18th century, a family of Kenski nobles resided in the town of Lublin, in eastern Poland. The patriarch of this family, Stanislaw Kenski (1725-1798), was a prominent landowner and served as a member of the local council.
Another noteworthy figure was Franciszek Kenski (1777-1842), who was a Polish military leader during the Napoleonic Wars. He fought alongside Napoleon's forces and was awarded several medals for his bravery and leadership on the battlefield.
The name Kenski can also be found in some historical records from the town of Poznan, in western Poland. One such record mentions a blacksmith named Jakub Kenski, who lived in the late 17th century.
During the 19th century, the surname Kenski became more widespread across various regions of Poland, and it also began to appear in other parts of Europe due to migration and immigration patterns.

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
