Origin
Meaning and origin of Kolarich
The surname Kolarich is of Croatian origin and is believed to have originated in the late 16th or early 17th century. It is derived from the Croatian word "kolar," which means "wheelwright" or "maker of wheels." This suggests that the name was initially associated with a guild or trade related to the production of wheels for various purposes, such as transportation or machinery.
The earliest known records of the surname Kolarich can be traced back to the regions of Istria and Dalmatia, which were historically part of the Venetian Republic and the Austro-Hungarian Empire, respectively. The name was particularly prevalent in the coastal areas and islands of Croatia, where the trade of wheelwrights was essential for maritime activities and shipbuilding.
One of the earliest documented instances of the surname Kolarich appears in the parish records of the town of Poreč, Istria, in the late 17th century. The name is also found in several historical documents from the 18th and 19th centuries, including tax records, census lists, and military rolls.
Notable individuals with the surname Kolarich throughout history include Ivan Kolarich (1832-1903), a Croatian painter and academic who specialized in portraiture and religious scenes. His works can be found in various churches and galleries across Croatia and neighboring regions.
Another prominent figure was Matija Kolarich (1878-1952), a Croatian lawyer and politician who served as a member of the Dalmatian Diet and was actively involved in the Croatian National Revival movement during the late 19th and early 20th centuries.
In the field of literature, Marija Kolarich (1901-1987) was a renowned Croatian author and poet whose works explored themes of love, nature, and the human condition. Her poetry collections, such as "Pjesme" (Poems) and "Stihovi o ljubavi" (Verses on Love), gained widespread recognition and acclaim.
Historically, variations in the spelling of the surname Kolarich have been observed, including Kollarich, Kollaritsch, and Kollarik, often influenced by regional dialects and linguistic variations.
It is worth noting that the surname Kolarich has also been associated with several notable place names in Croatia, such as the village of Kolari on the island of Brač, which likely derived its name from the presence of wheelwrights or individuals bearing the surname in that area.

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 Kolarich surname at the time of the 2020 Census, not any inherent property of the name itself.
