Origin
Meaning and origin of Korzelius
The surname KORZELIUS has its origins in Lithuania, first emerging in the 16th century. It is derived from the Lithuanian word "korys," meaning "stump" or "tree trunk," suggesting that the name may have initially referred to someone who lived near a prominent tree stump or worked as a woodcutter.
One of the earliest recorded instances of the name KORZELIUS can be found in the Lithuanian State Historical Archives, where a document from 1587 mentions a landowner named Jonas Korzelius. This suggests that the name had already gained some prominence within Lithuanian society by the late 16th century.
During the 17th century, several KORZELIUS families were recorded in the Vilnius region of modern-day Lithuania. One notable example is Martynas Korzelius (1623-1701), a wealthy merchant who established a successful trading business in the city of Kaunas.
In the 18th century, the KORZELIUS name began to spread beyond Lithuania's borders. Petras Korzelius (1742-1815) was a prominent figure in the Polish-Lithuanian Commonwealth, serving as a military officer and later as a diplomat.
As the Lithuanian diaspora grew in the 19th and 20th centuries, the KORZELIUS name traveled further afield. Juozas Korzelius (1879-1945) was a Lithuanian-American engineer who made significant contributions to the development of early aviation technology.
Another notable figure was Antanas Korzelius (1899-1968), a Lithuanian painter and art educator who helped establish the Lithuanian Art Academy in Kaunas. His works are celebrated for their distinctive use of color and depictions of Lithuanian folk traditions.
While the KORZELIUS name has remained relatively uncommon compared to some other Lithuanian surnames, it has left a lasting mark on various fields, from commerce and diplomacy to art and engineering.

The bar chart below shows how Korzelius 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 Korzelius surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.

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