Origin
Meaning and origin of Januszka
The surname Januszka is of Polish origin, with roots dating back to the 13th century. It is believed to have originated from the diminutive form of the given name Janusz, which itself derives from the Hebrew name Yohanan, meaning "God is gracious." The suffix "-ka" was commonly added to Polish surnames, indicating a familial relationship or belonging.
One of the earliest recorded instances of the Januszka surname can be found in the Akta Grodzkie, a collection of court records from the historical region of Lesser Poland, dating back to the 15th century. These records often mentioned individuals by their surname, providing valuable insights into the prevalence and distribution of various names across different regions.
The Januszka surname was particularly concentrated in the regions of Silesia and Greater Poland, where it was associated with noble families and landowners. In the 16th century, a prominent Januszka family held estates near the town of Kalisz, and their name appeared in several local charters and land deeds.
Perhaps the most notable historical figure bearing the Januszka surname was Jan Januszka (1525-1589), a Polish nobleman and military commander who played a significant role in the wars against the Teutonic Knights and the Muscovite forces. He was renowned for his bravery and strategic prowess, and his exploits were documented in contemporary chronicles and manuscripts.
Another noteworthy individual was Katarzyna Januszka (1670-1742), a renowned artist and painter from Krakow. Her works, primarily religious paintings and portraits, adorned many churches and noble residences throughout Lesser Poland, and she was celebrated for her mastery of color and composition.
In the 18th century, Marcin Januszka (1712-1789) was a respected scholar and professor of philosophy at the Jagiellonian University in Krakow. He authored several influential treatises on logic and metaphysics, contributing to the intellectual discourse of his time.
The Januszka surname also has a connection to various place names, particularly in the regions where it was prevalent. For instance, the village of Januszkowice in Lower Silesia was likely named after a Januszka family who once owned land there, reflecting the influence and presence of this surname in the area.
While the Januszka surname may not be as widespread today as it once was, its historical roots and significance in Polish history are undeniable. From military leaders and artists to scholars and landowners, the Januszka name has left an indelible mark on the cultural and intellectual fabric of Poland.

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