Although I have looked up people who live in South Africa many times at familysearch.org there has been very little success. There may be another resource for genealogy information about those who lived in South Africa, but I have not found it.
Once again, based on your most recent request, I tried to find John Christo Bennett born 1/10/1908 and baptized 17/1/1909, in South Africa. The result was, as has been the case many other times, that the name was not at familysearch.org .
Maybe someone else knows a resource that has family history info for South Africa. If so, I hope they will step forward.
