Please check out my latest guest article on the JewishGen Blog:
JewishGen Basics: JewishGen Online Worldwide Burial Registry (JOWBR)
In the article I cover how to use JOWBR to find graves all over the world (there are over 1.5 million records in JOWBR), as well as other Jewish cemetery resources including JewishData.com, CemeteryScribes.com, MountOfOlives.co.il, DeathIndexes.com and many more.
