Origin
Meaning and origin of Jarosch
The surname Jarosch is of German-Slavic origin, tracing its roots back to the regions of Silesia and Bohemia during the late medieval period. The name is believed to have derived from the Slavic personal name "Jaroch," itself a diminutive form of the name "Jaromir" or "Jaroslaw," which translates to "grand" or "glorious peace."
One of the earliest recorded instances of the name can be found in the tax records of the town of Breslau (now Wrocław, Poland) from the 15th century, where a certain "Hans Jarosch" is listed as a resident. In the same century, the name also appears in various church registers and land deeds in the neighboring regions of Bohemia and Moravia.
The Jarosch surname likely spread throughout Central Europe during the 16th and 17th centuries, as migrations and population movements became more common. Notable bearers of the name from this era include Johann Jarosch (1556-1621), a renowned clockmaker and inventor from Prague, and Katharina Jarosch (1603-1676), a midwife and herbalist from the town of Zittau in Saxony.
As the centuries progressed, the Jarosch name continued to disperse across the German-speaking lands and beyond. In the 18th century, a certain Friedrich Jarosch (1712-1778) gained recognition as a skilled woodcarver and sculptor in the city of Augsburg, Bavaria. Meanwhile, in the 19th century, the composer and organist Joseph Jarosch (1819-1888) made his mark in the musical circles of Vienna, Austria.
Venturing further afield, the 20th century saw the Jarosch surname carried to various corners of the globe by emigrants and their descendants. One notable figure was the American painter and educator Lorser Jarosch (1892-1986), whose works are held in numerous museum collections across the United States.
While the Jarosch surname may have originated in a specific region of Central Europe, its long and varied history has seen it become a truly international name, carried by individuals from diverse backgrounds and walks of life.

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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Jarosch surname at the time of the 2020 Census, not any inherent property of the name itself.
