Widow Eva Müller and her children arrived from Lübeck at the port of Oranienbaum on 4 July 1766 aboard the ship Die Neue Freiheit von Bremen under the command of Skipper Steingrawer.
They settled in the Volga German colony of Hildmann and are recorded there on the 1767 census in Households No. 5 and 43.
In 1790, Nikolaus Müller moved from Hildmann to Pfeifer.
The Oranienbaum passenger list records that Eva Müller and her family came from the German region of Hanau while the 1767 census records that her son Johann Müller came from the German region of Hannover.
