Origin
Meaning and origin of Boinski
The surname Boinski is of Polish origin, and it is believed to have emerged in the late 16th century. The name is derived from the Polish word "boisko," which means "field" or "meadow." This suggests that the earliest bearers of this surname were likely farmers or landowners who resided in or near a field or meadow.
One of the earliest recorded instances of the Boinski name can be traced back to a document from the town of Bialystok, located in present-day northeastern Poland. The document, dated 1587, mentions a certain Jan Boinski who was a landowner in the region. This provides evidence that the name was already in use during the late 16th century.
In the 17th century, the Boinski name appears in several historical records from various regions of Poland. For instance, a record from the town of Lublin, dated 1625, mentions a merchant named Andrzej Boinski. Additionally, a birth record from the city of Krakow, dated 1679, lists a child named Katarzyna Boinska, whose parents likely carried the Boinski surname.
During the 18th century, the Boinski name gained further prominence, particularly in the region of Galicia, which was then part of the Polish-Lithuanian Commonwealth. One notable figure from this period was Jakub Boinski (1725-1801), a respected scholar and author who wrote extensively on topics related to Polish history and culture.
In the 19th century, several individuals bearing the Boinski surname made significant contributions to various fields. For example, Tomasz Boinski (1810-1878) was a renowned architect who designed several notable buildings in Warsaw, including the iconic Polish National Opera. Another notable figure was Maria Boinska (1845-1915), a pioneering educator and advocate for women's rights in Poland.
As the Boinski name spread across Poland and beyond, it underwent various spelling variations, such as Boyinski, Boynski, and Bojenski. These variations often reflected regional dialects or phonetic adaptations. Additionally, some branches of the Boinski family adopted different surnames over time, further contributing to the name's diversity.
Throughout its history, the Boinski surname has been carried by individuals from various walks of life, including farmers, merchants, scholars, artists, and professionals. While its origins can be traced back to the late 16th century in Poland, the name has since spread to other parts of the world due to migration and cultural exchange.

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.
