The Genealogical Society of South Africa
The Genealogical Society of Utah (GSU), an organ of the Latter Day Saints (LDS), has published a collection of black and white photographs of a number of South African church registers here: Historical Record Collections - Africa
One of these collections is listed as South Africa, Dutch Reformed Church Registers, 1660-1970. In fact these appear to be church registers of the Nederduits Gereformeerde Kerk (NGK) from that denomination's archive, The NG Kerkargief, Noordwal-Wes, Stellenbosch, South Africa.
There is an index in the process of being compiled, also called:
Items found in that index link to the following, but there is no information as to whether these are all completely indexed or not.
(The Cape Town NGK baptisms 1653 to 1712, and the marriageas 1656 to 1712 are available in transcript among the eGGSA Transcripts)
STELLENBOSCH NGK church registers
(The Stellenbosch baptisms 1688-1732, and
The Stellenbosch burials 1765-1946
can be found transcribed and searchable on the eGGSA BDM Project pages - see the menu on the left of this page )
Tulbagh Marriages 1899-1911
(The Tulbagh baptisms and marriages prior to 1800 can be found transcribed and searchable on the eGGSA BDM web site - see the menu on the left of this page)
A further collection of NGK church register photographs exists, which had been indexed, with links, to all the various films which were in no sort of order on the LDS site, but the LDS has now re-arranged these, sorting them by place, still without any indication of what congregation or particular church the registers come from, and changed all the links so that the previous work done by Gwyneth Thomas and Lea Herbst has now been made useless.
This collection has been relabelled:
and is described thus:
Images of baptisms, confirmations, marriages, deaths, and memberships of the Dutch Reformed Church [Nederduits Gereformeerde Kerk In Afrika] housed at the Genealogical Institute of South Africa [Genealogiese Instituut van Suid-Afrika] Archive at Stellenbosch, South Africa.
In fact they are images of the church registers housed and maintained in the NGK Archives, Noordwal, Stellenbosch. GISA, mentioned above, is an LDS Family History Centre housing LDS films. It is not an archive and it does not house the original records, as suggested in the misleading statement quoted above.
