Lebrecht Gräf, a single man, arrived from Lübeck at the port of Oranienbaum on 8 August 1766 aboard the snow-brig Der Merkur under the command of Skipper Johann Heinrich Abelmann.
He settled in the Volga German colony of Urbach on 13 July 1767 and is recorded there on the 1767 census in Household No. 22.
In 1786, Johann Karl Graf and his brother Christoph moved from Schäfer to Urbach.
The Oranienbaum passenger list records that Lebrecht Gräf was a cobbler from the German region of Sachsen (Saxony). The 1767 census records that he was a farmer from the German village of Mansfeld.
