Jacob, Levi - Lauchringen is mentioned 22 times between 1725 and 1750. His designation in the Stühlingen family tree is 'L6'.
Jacob Levi does not belong to any of the Stühlingen Jewish family. He seems to have lived in Unterlauchringen without a letter of protection, but only a letter of passage. One might infer that he was resident somewhere else, but stayed in Unterlauchringen for `business`. The situation is atypical, because quite a few Jews were under protection in Unterlauchringen .
