Tara,

I've had good results with two South African websites:

SA Jewish Rootsbank, the South African Jewish Database
National Archives of South Africa

FamilySearch has some South African records, but I'd recommend starting with these two websites.  Many Jews emigrated to South Africa from Latvia and Lithuania.
