Origin
The surname Komarnicki is of Polish origin, derived from the word "komar" which means mosquito in Polish. It is believed to have originated in the 16th or 17th century as a descriptive name for someone who lived near a mosquito-infested area or worked as a trader in mosquito nets or repellents.
One of the earliest recorded instances of the name can be found in the Polish parish records from the town of Brzeżany (now in Ukraine) in the late 17th century. The name appears to have spread from this region to other parts of Poland and neighboring countries.
In the 19th century, the Komarnicki name was prominent among the Polish nobility and landowners. Tytus Komarnicki (1799-1886) was a Polish nobleman and politician who served as a member of the Galician Diet and the Austro-Hungarian Parliament.
Another notable figure was Roman Komarnicki (1886-1969), a Polish legal scholar and professor at the University of Warsaw. He was a leading expert in administrative law and served as the rector of the university from 1936 to 1939.
In the 20th century, Andrzej Komarnicki (1923-2008) was a renowned Polish mathematician and computer scientist. He made significant contributions to the fields of computational complexity theory and theoretical computer science.
The name Komarnicki can also be found among Polish immigrants who settled in various parts of the world, including the United States and Canada. For example, Józef Komarnicki (1875-1949) was a Polish-American businessman and philanthropist who founded the Komarnicki Engineering Company in Chicago.
Another noteworthy individual was Jan Komarnicki (1892-1937), a Polish military officer and diplomat who served as the Polish ambassador to the Soviet Union in the 1930s. He was tragically executed during the Great Purge under Joseph Stalin's regime.
While the surname Komarnicki is not among the most common Polish surnames, it has a long and interesting history, reflecting the diverse backgrounds and achievements of those who have borne this distinctive name.
Demographics
Among Census respondents with the surname Komarnicki, the largest self-reported group is White at 91.5%. The next largest groups are Hispanic (6.6%) and American Indian/Alaska Native (1.9%).
The bar chart below shows how Komarnicki 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 Komarnicki surname at the time of the 2020 Census, not any inherent property of the name itself.
