According to the information of my long-deceased father, Josef Brandl, is the name Brandl originally from the Black Forest and the same meaning as "Kohler" have. It was thus in the Middle Ages to people who burned charcoal in the forest (ie Brandl s). On the other hand, the name should also have the meaning Losbrenner so-Walker, which it never could stand long in one place, restless spirits up.
