Father is Gert Oosthuysen - daughter is Susanna Catrina Hester Hermina Oosthuysen was born about 3 Aug 1892

I need help opening up this Oosthuysen branch that was living in Ladysmith, Natal area before 1911 ... the father is listed simply as Gert Oosthusyen on his daughter's marriage register?

Susanna Catrina Hester Hermina Oosthuysen
was born about 3 Aug 1892
& her father is Gert Oosthuysen

So I would appreciate help with identifying Gert Oosthusen his wife & parents ... Thanks :)
