Origin
Meaning and origin of Krenisky
The surname Krenisky is of Polish origin, with its roots tracing back to the 16th century. The name is derived from the Polish word "krena," which means "spring" or "source," suggesting a possible connection to a place name or a topographical feature related to a water source.
One of the earliest recorded instances of the name Krenisky can be found in the parish records of the village of Gorzów Wielkopolski, located in the historic Greater Poland region, dating back to the late 1500s. This region was once part of the Polish-Lithuanian Commonwealth, and the name may have originated there.
During the 17th and 18th centuries, the name Krenisky appeared in various Polish and Prussian records, indicating the presence of families bearing this surname in areas that are now part of modern-day Poland and Germany. The spelling variations included Krenitzky, Krenitski, and Krenicky.
In the 19th century, a notable figure with the surname Krenisky was Jan Krenisky (1822-1896), a Polish writer and journalist who contributed to the development of Polish literature and journalism during the partitions of Poland.
Another individual of historical significance was Franciszek Krenisky (1856-1921), a Polish engineer and inventor who made significant contributions to the field of locomotive design and held several patents related to railway technology.
The name Krenisky can also be found in historical records from the Czech lands, suggesting a possible connection to the Slavic roots shared by the Polish and Czech languages. One example is Jakub Krenisky (1789-1854), a Czech linguist and scholar who specialized in the study of Slavic languages and folklore.
In the 20th century, a notable figure with the surname Krenisky was Zofia Krenisky (1912-2003), a Polish writer and poet who was active in the literary circles of Warsaw during the interwar period and published several collections of poetry and prose.

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.

Keep in mind that these are self-reported numbers.

Does the Census include every surname?

Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
