Origin
Meaning and origin of Petrykowski
The surname Petrykowski originates from Poland, with roots dating back to the medieval period. It is a locational name, derived from the Polish town of Petrykozy, located in the region of Malopolska. The name itself is believed to have evolved from the Slavic word "petryk," meaning "little stone."
One of the earliest recorded instances of the Petrykowski surname can be traced back to the 15th century, when a certain Jan Petrykowski was mentioned in a historical document from the town of Krakow. This document, which was a record of land transactions, suggests that the Petrykowski family held some prominence in the region during that time.
In the 16th century, the Petrykowski name appeared in several church records from the village of Petrykozy, indicating that the family had established roots in the area from which their name originated. These records often listed variations in spelling, such as Petrykovski or Petrykowsky, reflecting the fluid nature of surnames during that period.
A notable figure bearing the Petrykowski name was Andrzej Petrykowski (1637-1701), a Polish nobleman and military leader who fought in the Polish-Swedish War of the mid-17th century. He was renowned for his bravery and tactical skills, and his exploits were documented in several historical accounts of the time.
Another prominent Petrykowski was Katarzyna Petrykowska (1788-1865), a Polish philanthropist and advocate for women's education. She established several schools for girls in the region of Galicia, which was then part of the Austrian Empire. Her efforts were recognized by the Austrian authorities, and she received numerous honors for her contributions to society.
In the 19th century, the Petrykowski name can be found in various records from the regions of Silesia and Pomerania, which were then part of the Prussian Empire. This suggests that members of the Petrykowski family had migrated to these areas, likely in search of better economic opportunities or due to political upheaval.
One such example is Stanislaw Petrykowski (1826-1891), a Polish-Prussian industrialist who established a successful textile manufacturing business in the city of Bydgoszcz (then part of Prussia). He was known for his innovative business practices and philanthropic efforts, which earned him recognition from both Polish and Prussian authorities.
As the Petrykowski surname spread across Poland and into neighboring regions, it underwent various spelling variations, such as Petrykovsky, Petrykowicz, or Petrykowsky. These variations reflect the influences of different languages and cultural traditions on the evolution of the name.

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