Check the JewishGEN Given Names Database (GNDB) for Zusman and you'll
see it has been used as a kinnui for Azreyl, Eliezer, Imanueyl,
Meshulam, Yekusieyl, and Yoeyl, and as a variant of Zisman. Each of
the root names has a number of variations, nicknames, and spellings,
as does Zusman itself (17, in fact, just for Zusman). The GNDB is an
invaluable resource provided for free to the public by JewishGEN at
http://www.jewishgen.org/databases/GivenNames/search.htm.
