Hassler
A German surname most likely built from a short personal name such as Hademar, meaning “descendant of” or “one associated with” that name.
The #7,397 most common surname in the United States (2010 Census) — about 1 in every 68,625 Americans shares it.
Etymology
The historical sources point to Hassler as an old German surname formed from a personal name, especially a short form of Hademar. In that reading, the surname originally meant something like “son of Hademar” or “family of Hademar.” The ending -ler is common in German surnames and often marks a relationship to a person, place, or household rather than a literal occupation.
History
German surname scholars of the 19th century discussed Hassler among the many southern German names ending in -ler, and one source explicitly connects it with Hademar. The name is found in German-speaking areas and later appears in immigrant communities in North America. Because similar-looking surnames can sometimes have more than one local origin, the exact line of descent may vary by family.

Fun fact
One historical discussion grouped Hassler with a set of old Bavarian family names that were thought to come from older personal names rather than from occupations or nicknames.
