KLOTZ was initially a descriptive nickname given to individuals with a stocky or robust build. Over time, it evolved into a hereditary surname passed down through generations. The name was particularly prevalent in southern and central Germany, including regions like Bavaria, Baden-Württemberg, and Saxony.

One of the earliest recorded instances of the surname KLOTZ appears in the Codex Diplomaticus Saxoniae, a collection of historical documents from Saxony, where a man named Konrad Klotz is mentioned in a record from 1287.

In the 14th century, the KLOTZ surname is found in various medieval records and manuscripts, such as the Nuremberg Chronicle, a famous illustrated world history book published in 1493. This suggests that the name had gained widespread recognition by that time.
