Jacob, Bloch is mentioned 18 times between 1735 and 1743. His designation in the Stühlingen family tree is 'C2.1.4.2.4'. His father was Salomon (Rabbi), Bloch.
Jacob 's descendancy is not certain. Based on naming patterns, it is likely that Jacob was the son of Salomon ben Jacob Bloch. This is supported further by the fact that Salomon as rabbi didn`t have to pay protection tax [R5; 06.11.1717]. His son, therefore, didn`t have an automatic claim on a protection slot, and had to purchase it [R4623; 06.21.1735] . He bought himself a letter of protection in Horheim for 120 fl. [R4623; 06.21.1735]. He paid his protection tax without delay. An occupation is not apparent. .
