Origin
Meaning and origin of Mlady
The surname MLADY is believed to have originated in the Czech Republic, dating back to the early 15th century. It is derived from the old Czech word "mlada," which means "young" or "youthful." This suggests that the name may have been a descriptive nickname given to someone who appeared particularly young or had a youthful demeanor.
During the Middle Ages, it was common practice for people to adopt surnames based on physical characteristics, occupations, or places of origin. The use of the name MLADY can be traced back to various regions of modern-day Czech Republic, particularly in the areas around Prague and Bohemia.
One of the earliest recorded instances of the surname MLADY can be found in the Czech manuscript "Codex Gigas" (also known as the Devil's Bible), which dates back to the early 13th century. Although the manuscript itself does not explicitly mention individuals with the surname, it provides valuable insights into the linguistic and cultural context of the time.
In the late 15th century, a notable figure named Jan MLADY (born around 1460 in Prague) gained recognition as a skilled craftsman and woodcarver. His intricate works can still be seen in several churches and cathedrals across the Czech Republic.
Another prominent individual with the surname MLADY was Václav MLADY (1520-1578), who served as a court physician to the Holy Roman Emperor Maximilian II. Václav's medical treatises and contributions to the field of medicine during the Renaissance period are well-documented in historical records.
During the 17th century, the name MLADY appeared in various land ownership records and legal documents in the region of Moravia. One such record from 1642 mentions a landowner named Zikmund MLADY, who owned a sizable estate near the town of Olomouc.
In the 18th century, a notable military figure named Karel MLADY (1725-1802) gained prominence for his service in the Austrian army during the Seven Years' War. He rose through the ranks and eventually became a respected commander, leading troops in several battles against Prussian forces.
The surname MLADY has also been associated with several place names in the Czech Republic, such as the village of Mladý (meaning "young" in Czech), which is located near the town of Frýdek-Místek in the Moravian-Silesian Region. This further reinforces the connection between the surname and its linguistic roots.

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