Origin
The surname Ziemkowski finds its origins in Poland, with the name likely emerging in the medieval period. Poland, with its complex history of nobility and shifting borders, often saw surnames derived from toponyms—place names—or descriptive terms related to the natural environment or occupations.
Ziemkowski is most likely derived from a place name, specifically from locations named Ziemkowo or Ziemków, which are relatively common village names in various regions of Poland. The “-owski” suffix in Polish surnames generally signifies "from" or "belonging to," indicating that Ziemkowski means "from Ziemkowo." The root "ziem-" could be linked to the Polish word "ziemia," meaning "land" or "earth," suggesting a connection to someone who worked the land or was associated with a particular piece of land.
Historical records from the 15th and 16th centuries might include variations of the name, such as Ziemkowsky or Ziemkovski, given the fluid nature of spelling during those times. One of the earliest mentions of a similar surname appears in local church records from the 1500s, where a Jan Ziemkowski is cited as a landowner in the Greater Poland region. These records highlight the prominence of the name within rural communities, often associated with farming and agriculture.
In the 17th century, a notable figure, Stanisław Ziemkowski, emerges in historical documents as a minor noble who participated in the defense of Polish territories against Swedish invasions during the Deluge (1655-1660). Another significant bearer of the surname was Katarzyna Ziemkowska, born in 1701, who became well-regarded in her community for her charitable works and contributions to the local church in Pomerania.
Fast forward to the 19th century, records identify Michał Ziemkowski, born in 1824, a prominent figure in the Koszalin area known for his efforts in local politics and his advocacy for agricultural reform. His work in the late 1800s had a lasting impact on the development of more modern farming techniques in the region.
Aleksander Ziemkowski, born in 1883, stands out in the annals of Polish educational history. He was an influential teacher and author in Warsaw, fostering modern educational practices during the interwar period. His writings and pedagogical methods left a significant mark on Polish education, emphasizing critical thinking and a scientific approach to learning.
Throughout history, the surname Ziemkowski has been borne by individuals who contributed to their communities in various meaningful ways. From landowners and minor nobility to educators and reformers, the name has a rich tapestry of historical significance within Poland. Each person carrying the surname has, in their own way, reflected the cultural and social changes occurring in the regions they inhabited.
Demographics
Among Census respondents with the surname Ziemkowski, the largest self-reported group is White at 87.9%. The next largest groups are Two or More Races (7.1%) and Hispanic (4.0%).
The bar chart below shows how Ziemkowski bearers described their own race and ethnicity on the 2020 Census form. 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 Ziemkowski surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
