Origin
The surname Kurdy is of Czech origin, originating from the region of Bohemia in the 14th century. It is believed to derive from the Czech word "kurda," which means a type of curved or hooked knife or dagger. This suggests that the name may have initially referred to someone who made or carried such a weapon.
One of the earliest recorded instances of the name Kurdy can be found in the records of the town of Kutná Hora, located in central Bohemia. These records, dating back to the late 1300s, mention a blacksmith named Jan Kurdy who was known for his skill in forging blades and knives.
In the 15th century, the name Kurdy appeared in the municipal records of the city of Prague. These records refer to a merchant named Václav Kurdy, who dealt in various goods, including weapons and armor. This suggests that the name may have been associated with the trade of arms and military equipment during that time.
During the 16th and 17th centuries, the surname Kurdy spread across other parts of the Czech lands, including Moravia and Silesia. Several notable individuals bearing this name emerged during this period, such as Jindřich Kurdy, a renowned architect who designed several churches and palaces in the city of Olomouc in the late 16th century.
Another prominent figure with the surname Kurdy was Jan Kurdy, a Czech military commander who fought in the Thirty Years' War (1618-1648). He served under the command of Albrecht von Wallenstein and played a significant role in several battles during the conflict.
In the 18th century, the Kurdy surname appeared in various records from the region of Bohemia, including land registries and tax records. One notable individual from this period was Karel Kurdy, a wealthy landowner and patron of the arts, who commissioned several works of art and literature from prominent Czech artists and writers of the time.
As the Kurdy family continued to spread across the Czech lands, the name underwent some variations in spelling, such as Kurdi, Kurdý, and Kurděj. However, the original form of Kurdy remained the most commonly used throughout history.
Throughout the centuries, several other notable individuals have carried the surname Kurdy, including Václav Kurdy, a Czech politician and diplomat in the 19th century, and Jaroslav Kurdy, a renowned Czech composer and musician in the 20th century.
Demographics
Among Census respondents with the surname Kurdy, the largest self-reported group is White at 85.0%. The next largest groups are Two or More Races (11.0%) and Asian/Pacific Islander (4.0%).
The bar chart below shows how Kurdy 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 Kurdy surname at the time of the 2020 Census, not any inherent property of the name itself.
