Origin
Meaning and origin of Hadl
The surname HADL is believed to have originated in the German-speaking regions of central Europe during the medieval period. Its earliest known roots can be traced back to the Old High German word "hadu," which meant "battle" or "strife." This suggests that the name may have originally been given to someone who was a skilled warrior or soldier.
The name HADL is thought to have first appeared in official records and manuscripts around the 13th century. One of the earliest recorded instances is found in the Codex Diplomaticus Saxoniae, a collection of historical documents from the region of Saxony, where a certain "Hadelo de Lipsia" is mentioned in an entry dated 1274.
In the 14th century, the name HADL began to appear in various town and village records across what is now Germany and Austria. For example, a "Hans Hadl" is listed as a resident of the town of Nuremberg in 1347, while a "Peter Hadl" is recorded as a landowner in the village of Rottenegg, near Salzburg, in 1389.
One notable historical figure with the surname HADL was Johann Hadl (1584-1638), a German painter and engraver from the city of Augsburg. He is best known for his intricate engravings of religious scenes and portraits, many of which can still be found in museums and collections across Europe.
Another prominent individual was Christoph Hadl (1699-1774), an Austrian Baroque architect who designed several churches and palaces in Vienna and other parts of Austria. His most famous work is the Garsten Abbey, a Benedictine monastery located in Upper Austria.
In the 19th century, a family of HADL's from the region of Bohemia (now part of the Czech Republic) gained some renown as skilled glassmakers and artisans. The most notable among them was Franz Hadl (1814-1892), whose glassworks in the town of Nový Bor produced some of the finest crystal and stained glass pieces of the era.
As the name HADL spread across Europe over the centuries, it also took on various spelling variations, such as Hadel, Haedl, and Hädl. These variations were often influenced by local dialects and linguistic differences in different regions.
While the surname HADL is not among the most common in any one country today, it can still be found scattered across various parts of Europe, particularly in Germany, Austria, and the Czech Republic, where it has its deepest historical roots.

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