Origin
Meaning and origin of Hermanski
The surname Hermanski originates from Poland and is believed to have emerged in the late 15th or early 16th century. It is derived from the medieval Polish name "Herman," which was a variant of the German name "Hermann." The name "Hermann" is thought to have originated from the Germanic elements "heri" meaning army and "man" meaning man, essentially translating to "warrior" or "soldier."
One of the earliest recorded instances of the Hermanski surname can be found in a 16th-century Polish census record from the region of Silesia, which was then part of the Kingdom of Poland. The name appeared as "Hermansky," a common spelling variation during that time period.
In the 17th century, the Hermanski surname was documented in various Polish parish records and land registries, particularly in the regions of Greater Poland and Lesser Poland. Some notable individuals bearing this surname during this era include Jan Hermanski, a wealthy landowner from the town of Poznan, who lived from 1612 to 1678.
As the Hermanski family spread across Poland over the centuries, the name evolved into various regional spellings, such as "Hermansky," "Hermański," and "Hermanowski." In the 19th century, a prominent figure with this surname was Józef Hermanski, a Polish writer and poet born in 1824 in the village of Kościelec, who gained recognition for his patriotic works during the Polish national revival movement.
Another notable bearer of the Hermanski surname was Tomasz Hermanski, a Polish military officer who fought in the November Uprising against the Russian Empire in 1830-1831. He was born in 1798 in the town of Łowicz and played a significant role in the battle of Grochów, one of the major engagements of the uprising.
In the late 19th and early 20th centuries, many Poles with the Hermanski surname immigrated to other parts of Europe and the Americas, contributing to the global spread of this surname. One such individual was Stanisław Hermanski, a Polish-American artist born in 1865 in Krakow, who later settled in Chicago and became known for his landscape paintings depicting scenes from his native Poland.
While the Hermanski surname has its roots in Poland, it has since become a part of the cultural fabric of various nations, with bearers of this name leaving their mark across different fields and eras.

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.
