Then there are two other children baptised from Rosina Dorinda Van De Caap with no father listed

Dutch Reformed Church Cape Town
Age given as 5, mother given as Dorinda van de Kaap
This is where his brother Johan Coenraad appears to be baptised again
Internet gen trees suggest that Rosina Dorinda died in Swellendam in 1792.
I haven’t been able to confirm this but internet trees suggest Johan Coenraad Steyn married Susanna (Anna) Margaretha Van De Caap on 27 Jan 1793
