The first member of the
Hahn family is mentioned in the historical annals is Eckhard,
Eggehardus Gallus in Latin original. In 1230
he is referred to as a councilor and a knight of the Duke Johann the I-st of Mecklenburg and was, most probably, a descendent of the
Obodrite nobility – for centuries allies of
Charlemagne in his wars against the Germanic
Saxons and the Slavic
Veleti.
Our branch of the family starts from
Johann August von Hahn (1730 – 1791), Postmaster General during the reign of
Catherine the Great of Russia. The current owners of the Weissenburg Manor/ Kloster Zscheiplitz descend both from the Lutheran and Orthodox lines of the family: the first incorporated into the Ösel's Nobility Corporation in 1849, and the second (Gan;
рус. Ган) – members of the St. Petersburg nobility.
Hahn of Weissenburg family also preserves and represents the legacy of the barons
Knabenau – a junior line of the
Counts of Kyburg, a brunch of the
Agilolfing dynasty and direct descendant of the
Carolingian and
Ottonian dynasties, as well as houses of
Billung and
Habsburg-Laufenburg.
