Origin
Meaning and origin of Piskorz
The surname Piskorz has its origins in Poland, with records dating back to the 16th century. It is derived from the Polish word "piskorz," which means "loach," a small freshwater fish. This suggests that the name may have been given to someone who caught or traded in these fish, or perhaps lived near a body of water where they were found.
One of the earliest recorded instances of the Piskorz surname appears in the Akta Metrykalne, a collection of parish records from the Polish-Lithuanian Commonwealth, dating back to 1598. These records mention a Jan Piskorz from the village of Skrzynno, near present-day Warsaw.
In the 17th century, the name can be found in various historical documents from the Podlasie region of eastern Poland. One notable example is Wojciech Piskorz, a landowner from the town of Siemiatycze, whose name appears in a land deed from 1637.
As the Piskorz family spread throughout Poland over the centuries, variations in spelling emerged, such as Piskorski, Piskorzewski, and Piskorzyk. These variations often indicated a place of origin or the addition of a Polish surname suffix.
One of the earliest recorded examples of the name outside of Poland is found in the Prussian State Archives, which contain records of a Kasper Piskorz, a merchant from Gdańsk (Danzig) who was active in the late 17th century.
Throughout history, there have been several notable individuals with the Piskorz surname. These include:
1. Józef Piskorz (1811-1875), a Polish painter and lithographer known for his landscapes and historical scenes.
2. Piotr Piskorz (1875-1941), a Polish priest and activist who supported the Polish underground resistance during World War II.
3. Jadwiga Piskorz (1894-1986), a Polish writer and poet who wrote extensively about the struggles of women in rural Poland.
4. Władysław Piskorz (1905-1982), a Polish military officer and World War II veteran who fought in the Warsaw Uprising.
5. Kazimierz Piskorz (1924-2012), a Polish-born Canadian artist and sculptor known for his abstract works and public installations.
While the Piskorz surname may have humble origins, it has a rich history spanning centuries and has been borne by individuals from various walks of life, from artists and writers to military figures and resistance fighters.

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

Does the Census include every surname?

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