The history of the Erasmus family began in 1688, when Pieter Erasmus arrived in Cape Town in 1688. He settled into a farm called "Groenkloof", located in Drakenstein. Pieter married Maria Elisabeth Joosten in 1691. The couple had six children. Pieter roamed a great deal to look for cultivable land, a trait that his descendant,Daniel Jacobus Erasmus, inherited. It was Daniel Jacobus Erasmus who eventually occupied the land that in time became modern day Pretoria.
In 1841, the young Daniel Jacobus Erasmus arrived with his family in the area that is now Centurion. Like his ancestor Pieter, Daniel moved into a farm, which he named Zwartkop. But unlike his pioneering ancestor Daniel didn't find the farm site on his own. The place was recommended to him by his eldest son Daniel Elardus Erasmus. Elardus had happened into the area during an elephant hunt in 1831. He had found the area congenial for farming: There was great grazing grounds, pristine rivers and the absence of malaria. Taking his son's advice, Daniel bought a large piece of land and settled down.
