You might also find cemetery records to be helpful in your research. The JewishGen Online Worldwide Burial Registry (JOWBR) has collected information about thousands of Jewish cemetery sites worldwide. Each Jewish cemetery or burial site is listed by country, region/state, then city/town. Each listing includes the number of cemeteries in the city/town, the number of burials in each cemetery, and some cemetery listings even include photos. Keep in mind: the JOWBR depends on the continual contributions of data. So this means several Indiana Jewish cemeteries are not yet included in the registry.
