There are two Hoffmann families recorded from Schaffhausen. Their relationship to each other, if any, requires further research.
(1) In 1784, Karl Hoffmann and his family moved from Schaffhausen to Warenburg.
(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.
