The first Hahn, with whom this coat of arms is associated, 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, Minister of Post during the reign of Catherine II. 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 arms granted in 1791 by the Empress.
