Origin
Meaning and origin of Schleck
The surname SCHLECK has its origins in the German language and can be traced back to the late medieval period in central Europe. It is believed to have originated as a descriptive name, likely derived from the Middle High German word "schlecken," which means "to lick" or "to lap up." This suggests that the name may have been initially given as a nickname to someone with a distinctive way of eating or drinking.
One of the earliest recorded references to the name SCHLECK can be found in the town records of Nuremberg, Germany, dating back to the 14th century. In these records, a certain Hans Schleck is mentioned as a resident of the city in the year 1384. This provides evidence that the name was already well-established in the region at that time.
As the name spread across different parts of Germany and neighboring countries, it underwent various spelling variations, such as Schlecke, Schlecker, and Schleckmann. These variations often reflected regional dialects and the preferences of local scribes who recorded the names.
In the 16th century, the name SCHLECK appeared in several historical documents related to the Protestant Reformation. One notable figure was Johannes Schleck, a Lutheran pastor and theologian born in Saxony in 1516. He was known for his contributions to the development of Protestant theology and his works on biblical interpretation.
Another significant individual bearing the SCHLECK surname was Johann Schleck, a German composer and organist who lived in the 17th century. Born in 1629 in Meissen, Saxony, he is remembered for his compositions for the organ and his contributions to the sacred music of his time.
Moving forward to the 19th century, one can find references to the name SCHLECK in connection with the German diaspora to North America. For instance, Carl Schleck, born in 1823 in Bavaria, emigrated to the United States and became a prominent figure in the German-American community of St. Louis, Missouri.
In the 20th century, the name SCHLECK gained international recognition through the achievements of two professional cyclists from Luxembourg, Andy and Fränk Schleck. Andy Schleck, born in 1985, won the Tour de France in 2010 and finished second in 2009 and 2011. His older brother, Fränk Schleck, born in 1980, also achieved notable success in professional cycling, including a third-place finish in the Tour de France in 2011.
While the surname SCHLECK may have originated as a descriptive nickname, it has endured through centuries and has been carried by individuals who have made significant contributions in various fields, from religion and music to sports and community leadership.

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 Schleck 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.
