The surname Roski has its origins in Poland, where it first appeared in the 13th century. It is believed to have derived from the Polish word "roska," meaning "dew" or "moisture," suggesting that the name may have originally referred to someone who lived near a body of water or in a particularly damp area.

One of the earliest recorded instances of the name can be found in the Teutonic Knights' records from the 14th century, where a Roski family is mentioned as residing in the region of Pomerania, which was then part of the Monastic State of the Teutonic Knights.

In the 15th century, the name Roski appeared in the Akta Grodzkie, a collection of court records from the Krakow region of Poland. This suggests that the name had spread from its original location in Pomerania and had become more widely established throughout the country.

A notable bearer of the Roski surname was Jan Roski, a Polish noble who lived in the late 16th century. He was a member of the landed gentry and owned several estates in the region of Masovia, near present-day Warsaw.

Another prominent figure with this name was Marianna Roski, a Polish artist and painter who lived in the 18th century. She is best known for her portraits of the Polish aristocracy, many of which are now housed in various museums and galleries across Poland.

In the 19th century, the Roski name found its way to other parts of Europe, with several families immigrating to Germany and the Netherlands. One such individual was Wilhelm Roski, a German businessman born in 1845, who established a successful trading company in Hamburg.

As the 20th century dawned, the Roski name began to appear in various parts of the world, including the United States and Canada, where many Polish immigrants settled. One notable example is Eryk Roski, a Canadian physicist born in 1920, who made significant contributions to the field of quantum mechanics.

Throughout its long history, the Roski surname has maintained a strong connection to its Polish roots, with many bearers of the name still residing in Poland and other parts of Eastern Europe. While relatively uncommon outside of these regions, the name continues to carry the legacy of its origins, reflecting the diverse and rich cultural heritage of the Polish people.
