Hans Georg Mühlhaus, a farmer, and his family arrived from Lübeck at the port of Oranienbaum on 15 June 1766 aboard the ship Die Vergelte Weintraube under the command of Skipper Anderson.
They settled in the Volga German colony of Keller on 12 May 1767 and are recorded there on the 1767 census in Household No. 54.
Following the destruction of the colony of Keller, the Mühlhaus family relocated to the colony of Neu-Kolonie.
The 1767 census records that Johann Georg Mühlhaus came from the German village of Urlichstadt [?] in the Darmstadt region.
