Origin
Meaning and origin of Konchan
The surname KONCHAN originates from Poland, where it first emerged in the 12th century. It is believed to be derived from the Old Polish word "koncha," meaning "the end" or "the last." This suggests that the name may have been given to someone who lived at the end of a village or settlement.
KONCHAN is thought to have roots in the Silesian region of southwestern Poland, particularly in the areas around the cities of Wrocław and Opole. Early records show variations in spelling, including Konchani, Konchansky, and Konchanitz.
One of the earliest known references to the name KONCHAN can be found in a document from the Cistercian monastery in Lubiąż, dated 1237. The document mentions a landowner named Konrad Konchan, who donated a parcel of land to the monastery.
In the 14th century, a nobleman named Jan Konchan served as a knight under King Władysław II Jagiełło. He was noted for his bravery in battle against the Teutonic Knights during the Polish-Lithuanian-Teutonic War.
During the Renaissance period, a renowned scholar and humanist named Mikołaj Konchan (1460-1522) gained fame for his translations of ancient Greek texts into Latin. He taught at the University of Krakow and was a significant figure in the Polish intellectual circles of his time.
In the 17th century, a wealthy merchant named Stanisław Konchan (1620-1687) became a prominent figure in the city of Gdańsk (Danzig). He was involved in the lucrative trade of amber and established a successful business empire.
Another notable individual with the surname KONCHAN was Józef Konchan (1778-1857), a Polish military officer who fought in the Napoleonic Wars. He rose to the rank of general and was awarded the prestigious Virtuti Militari, Poland's highest military decoration.
While the KONCHAN surname may have originated in Poland, it has since spread to other parts of the world, particularly through emigration. However, its roots and historical significance remain deeply tied to the Polish nation and its rich cultural heritage.

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

Does the Census include every surname?

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