There are two Hoffmann families recorded from Schaffhausen. Their relationship to each other, if any, requires further research.
(1) Karl Hoffmann, a fur maker; his wife Eva; and children (Dorothea, age 4½; Regina, age 2½) arrived from Lübeck at the port of Oranienbaum on 10 August 1766 aboard a ship under the command of Skipper Nikolaus Peter Pink.
Carl Hoffmann, his wife Eva Maria, and daughter Catharina (age 4¾) are recorded on the list of colonists being transported from St. Petersburg to Saratov in 1767.
Johann Karl Hoffmann, a sheep skin tanner (Schaffelgerber), his wife Eva, and daughter Dorothea are recorded on the 1767 census of Katharinenstadt in Household No. 62 along with a note that they relocated to the colony of Schaffhausen in 1768. They had settled in Katharinenstadt on 3 August 1767.
In 1784, Karl Hoffmann and his family moved from Schaffhausen to Warenburg.
The 1767 census records that Johann Karl Hoffmann came from the German village of Reichenbach in the Schlesien (Silesia) region.
(2) Widow Elisabeth Hoffmann is recorded on the 1798 census of Schaffhausen in Household No. Sh51 along with a note that she had gone to Moscow and that her current whereabouts were unknown.
