Franz Dominikus Haeberlin taught philosophy and law at the former University of Helmstedt. One of the last four "Meistersingers" (literal "master singers") in Ulm was Johannes Haeberlen. In Stuttgart we also find the name in the 17th and 18th century: there the carriers were mainly business men. A member of their family was Georg Heinrich Haeberlin, who was professor of theology in Tuebingen at the end of the 17th century. His picture in oil is at the university, decorated with his coat of arms. Even among the relatives of Schiller we find the name: in 1731 the town-courier Johann Georg Haeberlin in Esslingen marries the sister of the poet's father; his descendants are Haeberles. These are just a few examples for the frequency and distribution of the name in Wuerttemberg.

Some of these families already have a thorough genealogy. For example Dr. Alfred Haeberle from Cottbus follow back the history of his family, which lives in and around Goeppingen until 1400. Their name was spelled the same as ours. The family circle in Altona-Othmarschen to which also the Tuttlinge line is connected, edits a family bulletin regularly. But connections to Weinsberg and our line have not appeared yet.

One could assume that a comparison of the coat of arms would lead to yet unknown connections with other family lines. About half a century ago Karl Haeberlen, mayor of Calmbach, had our coat of arms designed as seal by an expert seal maker, supposedly, but it cannot be proved by copying an old seal. It is shown on the title page consisting of three oats+ on three hills (Dreiberg?)(literal "three hills") under a helmet decorated with buffalo horns between which the picture of the three oats is repeated. All this is surrounded by rich helmet decorations. This coat of arms is a so called "telling coat of arms" because it gives an explanation for the name. The coats of arms which are listed in Siebmacher's book are also "telling coats of arms".
