Origin
Meaning and origin of Konarzewski
The surname Konarzewski is of Polish origin, tracing its roots back to the Middle Ages. It is believed to be derived from the Polish word "konarz," which means "a branch" or "a bough," possibly indicating that the name's bearers were originally from a wooded or forested area.
The earliest known records of the Konarzewski name date back to the 15th century, with references found in various historical documents and manuscripts from the region of Wielkopolska (Greater Poland). One notable mention is in the "Kodeks Dzikowski" (The Codex of Dzików), a medieval manuscript from the late 15th century, which lists several individuals with the surname Konarzewski.
In the 16th century, the name appeared in the "Metryka Koronna" (Crown Metrica), a collection of records documenting the administrative and legal affairs of the Polish-Lithuanian Commonwealth. This suggests that the Konarzewski family held a certain level of prominence during that period.
One of the earliest recorded individuals bearing the Konarzewski surname was Jan Konarzewski, a nobleman and landowner who lived in the late 16th century. He was known for his involvement in local politics and his role in the Polish-Lithuanian Commonwealth's military campaigns.
Another notable figure was Piotr Konarzewski (1590-1644), a Catholic priest and theologian who served as a rector at the Jagiellonian University in Krakow. He was renowned for his scholarly works on theology and philosophy.
In the 18th century, the Konarzewski name gained further recognition with Stanisław Konarzewski (1720-1789), a prominent Polish nobleman and military commander. He played a significant role in the Polish-Lithuanian Commonwealth's armed forces and was decorated for his valor during the wars against Russia and Prussia.
During the 19th century, the Konarzewski surname was associated with several notable individuals, including Józef Konarzewski (1814-1878), a renowned Polish writer and poet. His works captured the spirit of the Polish Romantic movement and explored themes of national identity and patriotism.
Another prominent figure from this era was Feliks Konarzewski (1846-1920), a Polish engineer and inventor. He was recognized for his contributions to the field of mechanical engineering, particularly in the development of early steam engines and industrial machinery.
These examples illustrate the historical significance and widespread presence of the Konarzewski surname across various regions of Poland and throughout different eras. While the name's origins can be traced back to the Middle Ages, its bearers have left their mark in various fields, including politics, religion, literature, and science.

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.

Keep in mind that these are self-reported numbers.
