Hermann Müller, a farmer, and his wife Elisabeth 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. 9.
The 1767 census records that Hermann Müller came from the German village of Heimbach in the region of Württemberg.
