Origin
Meaning and origin of Jaworek
The surname JAWOREK is of Polish origin and can be traced back to the 14th century. It is believed to have originated from the Polish word "jawor," which means "sycamore tree." This suggests that the name may have initially referred to someone who lived near a sycamore tree or in an area where these trees were abundant.
One of the earliest recorded instances of the name JAWOREK is found in a medieval Polish manuscript dating back to the 15th century, which mentions a landowner named Jan JAWOREK. This indicates that the name was already well-established by that time among the Polish nobility.
During the 16th and 17th centuries, the name JAWOREK appears in various historical records from the regions that are now part of modern-day Poland, including the areas of Silesia and Galicia. It is worth noting that the spelling of the name may have varied slightly during this period, with variations such as JAWORAK or JAWORKA being encountered.
A notable figure bearing the JAWOREK surname was Piotr JAWOREK, a Polish military leader who fought in the Polish-Muscovite War of 1609-1618. He was born in 1580 and died in battle in 1618, defending the city of Smolensk against Russian forces.
Another individual of historical significance was Katarzyna JAWOREK, a Polish noblewoman and landowner who lived in the 17th century. She was known for her philanthropic efforts and for supporting the construction of several churches and monasteries in the region of Lesser Poland.
In the 18th century, the JAWOREK name gained prominence in the field of education with the birth of Jan JAWOREK (1720-1789), a renowned Polish scholar and professor of philosophy at the University of Krakow.
Moving into the 19th century, a notable figure was Tomasz JAWOREK (1810-1892), a Polish writer and poet who contributed significantly to the development of Polish literature during the Romantic period.
Finally, in the early 20th century, Stanisław JAWOREK (1891-1965) was a prominent Polish architect who designed several iconic buildings in Warsaw, including the Warsaw Polytechnic and the National Museum.

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