Gottfried Hahn, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 18 June 1766 aboard the hooker Anna Catharina under the Skipper Adolph Scharpenberg.
They settled in the Volga German colony of Keller on 12 May 1767 and are recorded there on the 1767 census in Household No. 23.
The 1767 census records that Friedrich Hahn came from the German village of Heimerdingen in the region of Württemberg.
There are no known surviving male lines of this Hahn family among the Volga German colonies.
