The first Hahn is mentioned in the historical annals as Eckhard the I-st, or “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. Not much is known about his ancestors, though the family legend points to Franconia as a place of family’s origin.
Our branch of the family starts from Johann August von Hahn (1730 – 1791), Postmaster General during the reign of Catherine the Great of Russia. His discendants were incorporated into the Ösel’s Nobility Corporation in 1849 with the arms identical to that of the Coulrand branch. Further, the descendants of Johann August were also received into the St. Petersburg nobility with the Russian arms granted in 1791 by the Empress.
