https://familysearch.org/)
2. Click "Search"
3. Under "Browse all Published Collections" click "Africa"
4. Under "Historical Record Collections" on left menu under
"Collections" click "Birth, Marriage & Death"
5. On next page also entitled "Historical Record Collections" click
the 9th row "South Africa Natal Province Civil Marriages 1845-1955"
The URL address for this page is:
https://www.familysearch.org/search/collection/20637496. The page which opens gives you the ability to "Search Collection"
To test, I entered "Hazel Beryl ABBEY" clicked "Marriage" and clicked "Search"
7. Only 1 Result was found
8. Click on the underlined Hazel Beryl ABBEY (in red).
9. The next page shows the record about the Marriage.
10. On the right of the page is a button "." Click it.
