Jewish Online Worldwide Burial Registry (JOWBR) https://www.jewishgen.org/databases/cemetery/
This is a database of names and other identifying information from Jewish cemeteries and burial records worldwide, from the earliest records to the present. It is a compilation of three linked databases: a database of burial records, headstone photos when available, and information about each particular cemetery where burial records are available.
JOWBR is a searchable database on JewishGen, and the data is also incorporated into the relevant JewishGen “All Country” Databases.
