Origin
Meaning and origin of Stych
The surname "STYCH" is of Polish origin, tracing its roots back to the late 15th century in the region of Greater Poland. It is believed to have derived from the Old Polish word "styczen," which means "January," suggesting a possible connection to someone born or named during that month.
One of the earliest recorded instances of the name can be found in the historical records of the city of Poznan, where a certain Jan Stych was mentioned as a resident in the year 1487. This provides evidence of the name's existence and usage during the late medieval period in Poland.
In the 16th century, the name appears in various church registers and municipal documents across various towns and villages in the Polish-Lithuanian Commonwealth. Notable examples include Maciej Stych, a landowner from the village of Goluchow, documented in 1563, and Grzegorz Stych, a tradesman from the city of Kalisz, mentioned in a guild registry from 1587.
The name also has connections to place names, such as the village of Styczkow, located in the Łódź Voivodeship of central Poland. This village name, which shares a similar root to the surname "STYCH," dates back to the 13th century and is thought to have been derived from the personal name "Styczek," a diminutive form of the name.
Throughout history, several individuals with the surname "STYCH" have gained recognition in various fields. One notable figure was Jan Stych (1590-1653), a Polish Catholic priest and theologian who served as the bishop of Warmia and played a significant role in the Counter-Reformation efforts in Poland.
Another prominent bearer of the name was Józef Stych (1763-1835), a Polish military officer who served in the Polish Army during the Kościuszko Uprising against Russian forces in the late 18th century.
In the 19th century, Andrzej Stych (1826-1897) was a renowned Polish painter and art educator, known for his landscape and genre paintings depicting rural life in Poland.
The 20th century saw the rise of Wacław Stych (1914-1973), a Polish footballer who played as a defender for several clubs, including Cracovia and Warta Poznań, and represented the Polish national team in the 1938 FIFA World Cup.
More recently, Janusz Stych (born 1951) is a Polish mathematician and academic, renowned for his contributions to the field of functional analysis and his work as a professor at the University of Warsaw.

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.
