de Waal Malefijt

My name is Dick de Waal Malefijt and I am looking for the family tree of the Waal Malefijt.

My question is about 2 birth certificates from Elandsfontein, South Africa. Karel Everhard de Waal Malefijt emigrated with his wife Jemima van der Snel, On May 20, 1897, Jemima leaves from Aalsmeer where they had a plant and flower nursery with five children to South Africa to live in Elandsfontein. Karel Everhard is going to work at the South African railways. And also fights in the last Farmers War between 1899 and 1902. Two children are born in South Africa.

Two children are born in South Africa:
Dirk Leendert born 25-04-1898 in Elandsfontein;
and Karel Everhard Frederik Johannes Jr. Born 26-01-1900 in Elandsfontein.

Is it possible to get the birth certificates of the two children?

Kind regards Dick
