Origin
Meaning and origin of Konkoly
The surname KONKOLY is of Hungarian origin, tracing its roots back to the medieval period in Central Europe. The name is derived from the Hungarian word "konkoly," which translates to "cockle" or "corn-cockle," a type of weed that commonly grew among wheat fields.
This surname likely originated as a descriptive nickname for someone who lived near fields infested with these weeds or worked as a farmer tasked with removing the cockles from their crops. Variations in spelling, such as Konkolyi, Konkolyos, and Konkolicz, have also been recorded throughout history.
One of the earliest documented references to the KONKOLY name appears in a 14th-century manuscript from the town of Eger, located in northern Hungary. The record mentions a landowner named Péter Konkoly, who owned several acres of farmland in the region.
During the 15th century, the KONKOLY name gained prominence when János Konkoly (1420-1492) became a respected scholar and theologian at the University of Vienna. He authored several influential works on religious philosophy and played a significant role in the intellectual discourse of his time.
In the 18th century, Miklós Konkoly (1742-1816) was a prominent Hungarian nobleman and military officer who served in the Austrian army during the Napoleonic Wars. His bravery and leadership on the battlefield earned him several honors and distinctions.
The 19th century saw the rise of the renowned astronomer Miklós Konkoly-Thege (1842-1916), whose contributions to the study of celestial bodies and the advancement of astronomical instruments were widely recognized. He established the Konkoly Observatory in Budapest, which remains an important center for astronomical research to this day.
Another notable figure from this era was the poet and writer Ede Konkoly-Thege (1864-1927), who was acclaimed for his lyrical works and his efforts in preserving Hungarian folk traditions and culture.
In more recent times, the KONKOLY surname has continued to be associated with various fields, including science, literature, and the arts, further cementing its place in Hungarian history and culture.

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