HI, I am not convinced that he was the son of @Jan Andries Petrus CONRADIE, b1c1d5e1f3g3 , because he was not mentioned on his father's death notice completed by his father's second wife. https://www.familysearch.org/ark:/61903/3:1:3Q9M-C913-LTFF
I think there is a good chance that he is linked to the correct grandparents. After all they had 8 children together.
