Origin
Meaning and origin of Mosich
The surname MOSICH is believed to have originated in the region of modern-day Poland, dating back to the 12th or 13th century. It is thought to be derived from the Old Slavic word "moch," meaning "moss," which could have been used to describe a person's physical appearance or occupation. The earliest known records of the name appear in medieval Polish documents, often with variations in spelling such as Mosycz, Mosic, or Mosycki.
One of the earliest documented instances of the MOSICH surname can be found in the Liber Beneficiorum, a 14th-century manuscript that recorded the distribution of land and properties in the Archdiocese of Gniezno, Poland. This suggests that individuals bearing the MOSICH name were likely landowners or noble families during that time period.
In the 16th century, a notable figure with the MOSICH surname was Jan Mosich, a Polish nobleman and military commander who fought in the Polish-Muscovite War (1577-1582). His bravery and leadership during the conflict were recognized, and he was awarded lands and titles by the Polish king.
During the 17th century, the MOSICH name appeared in various records across Central and Eastern Europe, including in the Czech lands and the Kingdom of Hungary. One prominent individual was Andrzej Mosich, a Polish-Lithuanian architect who designed several churches and public buildings in the city of Vilnius, now the capital of Lithuania.
In the 19th century, a famous bearer of the MOSICH name was Józef Mosich, a Polish painter and illustrator known for his detailed depictions of landscapes and rural scenes. He was born in 1829 and spent much of his career in Warsaw, where he gained recognition for his work.
Another notable figure was Karol Mosich, a Polish writer and journalist who lived from 1867 to 1938. He was a vocal advocate for workers' rights and social reforms, and his writings played a significant role in shaping the political discourse of his time.
While the MOSICH surname originated in Poland, it has since spread to other parts of Europe and beyond, with individuals bearing the name making contributions in various fields throughout history.

The bar chart below shows how Mosich bearers described their own race and ethnicity on the 2020 Census form. 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 Mosich surname at the time of the 2020 Census, not any inherent property of the name itself.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
