Origin
Meaning and origin of Jedrzejek
The surname Jedrzejek originates from Poland and dates back to the late Middle Ages. It is derived from the Polish variant of the biblical name Andrew, which is Jędrzej. The suffix "-ek" is a diminutive commonly used in Polish surnames, indicating a familial relationship or a smaller version of something.
Jedrzejek is believed to have originated in the regions of Lesser Poland and Silesia, where it was initially recorded in various historical documents and records. One of the earliest known mentions of the name can be found in the Church Registry of Krakow from the 15th century, where a certain Maciej Jedrzejek was listed as a resident of the city.
In the 16th century, the Jedrzejek surname appeared in the Masovian Voivodeship, which was then part of the Polish-Lithuanian Commonwealth. A notable bearer of this name from that era was Jakub Jedrzejek, a merchant who traded goods along the Vistula River.
During the 17th century, the name Jedrzejek was recorded in the town of Opole, located in modern-day southwestern Poland. One of the earliest known bearers of this surname in Opole was Jan Jedrzejek, a blacksmith who lived and worked in the town's metalworking district.
The 18th century saw the emergence of several notable individuals bearing the Jedrzejek surname. One such person was Tomasz Jedrzejek, a Polish soldier who fought in the Bar Confederation uprising against the Russian Empire in the late 1760s.
In the 19th century, the Jedrzejek surname continued to appear in various regions of Poland. One prominent figure was Franciszek Jedrzejek, born in 1822, who was a renowned painter and artist known for his landscapes and portraits.
As the centuries passed, the Jedrzejek surname spread across Poland and beyond, with some bearers of the name emigrating to other parts of Europe and the Americas. However, it remains most closely associated with its Polish roots and the regions where it first emerged during the Middle Ages.

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

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