Origin
Meaning and origin of Augustynowicz
The surname Augustynowicz is of Polish origin, with its roots tracing back to the 16th century. It is a patronymic surname, derived from the personal name "Augustyn," which is the Polish equivalent of the name "Augustine." This name, in turn, originated from the Latin name "Augustinus," meaning "venerable" or "majestic."
The earliest records of the name Augustynowicz can be found in historical documents from the region of Masovia, a province located in central Poland. It is believed that the name first emerged in the area around the city of Warsaw, which was a prominent center of culture and trade during the Renaissance period.
One of the earliest known bearers of the surname Augustynowicz was Jan Augustynowicz, a prominent merchant and trader who lived in Warsaw in the late 16th century. His name appears in several trade records and legal documents from that time, indicating the significance of his business ventures.
During the 17th century, the Augustynowicz family gained prominence in the region of Podlasie, situated in eastern Poland. Several members of the family held positions of authority and influence within the local government and nobility. One notable figure was Piotr Augustynowicz, who served as a magistrate in the town of Biała Podlaska in the mid-17th century.
In the 18th century, the Augustynowicz surname spread further across Poland, with members of the family settling in various regions, including Silesia and Galicia. One notable bearer of the name during this period was Kazimierz Augustynowicz, a renowned scholar and philosopher who taught at the University of Krakow in the late 18th century.
The 19th century saw the Augustynowicz family continue to thrive, with several individuals making significant contributions in various fields. Józef Augustynowicz, born in 1810, was a prominent writer and poet who published several collections of poetry and prose during his lifetime.
Another notable figure was Stanisław Augustynowicz, born in 1865, who was a renowned architect and urban planner. He was responsible for designing several iconic buildings and public spaces in Warsaw and other major Polish cities.
As the Augustynowicz surname spread across Poland and beyond, it also gave rise to various variations and spellings, such as Augustynowic, Augustynowycz, and Augustynovich. However, the core meaning and origin of the name remained rooted in the personal name "Augustyn" and its Latin predecessor, "Augustinus."

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.
