[Johann] Gottlieb Holzhausen, a single miller (Müller), arrived from Lübeck at the port of Oranienbaum on 15 September 1766 aboard a ship under the command of Skipper Hans Karholm.
He settled in the Volga German colony of Boisroux on 3 August 1767 and is recorded there on the 1767 census in Household No. 36.
In 1797, Karl Holzhausen moved from Boisroux to Saratov.
The 1767 census records that Johann Gottlieb Holzhausen came from the German village of Schmiedenburg.
