Leonhard Stumpf, a cobbler (Schuhmacher), his wife Katharina, children (Katharina, age 3½; Jakob, age 2½), and his father-in-law Peter (also recorded with surname of Stumpf) arrived from Lübeck at the port of Oranienbaum on 18 June 1766 aboard the ship Mann und Frau under the command of Skipper Daniel Berg.
They settled in the Volga German colony of Warenburg on 12 May 1767 and are recorded there on the 1767 census [erroneously under the surname of Strömer] in Household No. 39.
The 1767 census records that Leonhard Strömer [sic] came from the German village of Oberaltenbernheim in the Kassel region.
