ysakowski

Ysakowski is a surname of Polish origin, primarily found in Eastern Europe and among the diaspora in North America and Australia. The name is derived from the root "ysłak," a diminutive of the first name "Ysil," a variant of the Slavic name Yvette, combined with the common suffix "-owski," which denotes belonging or origin. Historically, individuals bearing the name were often associated with rural communities in the Masovian and Łódź regions, where agricultural and artisanal occupations predominated.

In the 19th and early 20th centuries, many Ysakowski families emigrated to the United States in search of economic opportunities. They settled largely in industrial hubs such as Pittsburgh, Chicago, and New York, contributing to the growth of steel, coal, and textile manufacturing sectors. Later waves of migration after World War II further established Ysakowski communities in California and Ontario, where small family-owned businesses flourished.

Notable people with the surname include Adam Ysakowski (born 1965), a Polish-American economist known for his research on labor market dynamics in post-communist economies, and Katarzyna Ysakowska (1978–2015), a Polish journalist who reported on environmental policy for several national newspapers. While the name does not rank among the most common Polish surnames, it remains a distinct identifier within the Polish and broader Slavic diaspora.
