The surname "KRZECZKOWSKI" originated in Poland. It is a Polish topographic surname derived from the word "krzaczek," meaning "bush" or "shrub," combined with the suffix "-owski," which denotes a place of origin. This suggests that the name initially referred to someone who lived near or in an area with many bushes or shrubs.
The earliest recorded examples of this surname can be traced back to the 16th century in various Polish records and documents. One notable mention is in the "Ksiegi miejskie" (Town Books) of Krakow from the year 1537, where the name "Krzeczkowski" is listed among the residents of the city.
In the 17th century, a variant spelling of the name, "Krzeczkowski," appeared in the "Akta grodzkie i ziemskie" (Court and Land Records) of the Lublin region, dating back to 1643. This suggests that the name was present in different parts of Poland during that time.
One of the earliest known individuals with this surname was Jan Krzeczkowski, a merchant from the city of Poznań, born around 1580. He was mentioned in the city's trade records from the early 1600s.
Another notable figure was Jakub Krzeczkowski, a Polish philosopher and theologian who lived in the late 16th and early 17th centuries. He authored several works on ethics and moral philosophy, including "De virtutibus cardinalibus" (On Cardinal Virtues) published in 1612.
In the 18th century, the name "Krzeczkowski" appeared in the records of the town of Opole Lubelskie. One example is Franciszek Krzeczkowski, a landowner and local official, who was born in 1725 and died in 1798.

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.
