Natalie da Silva of the Genealogical Society of South Africa (www.genza.org.za) talks about all the records and resources available for researching South African ancestors. Plus South African history, immigration, how the country is setup, locations of archives, where records are stored and if they have been digitised and who to contact.  The accompanying blog post gives links to many of these: https://emmacox.co.uk/researching-your-ancestors-in-south-africa.
