Van Rooy or Van Rooij is a Dutch toponymic surname. "Rooij" was a local term for many towns ending with "rode" or "roij", like Nistelrode, Sint-Oedenrode, Stramproy and Wanroij. This suffix means "a clearing made by men".
Colonialisation caused an expansion of Europe into the rest of the world. South Africa saw many European/Dutch Settlers from the late 16 century to the 18th century. Along with the complex socio-geodemographic development that occurred in South Africa at the time, the van Rooy family name expanded in 2 directions within the racial context of the time. Attached (and to come) is the family tree of Pieter & Johanna van Rooy (maiden surname: Koordom) whom originated from Piketberg (RSA) and moved (circa 1920) to Cape Town (RSA). They reared 8 children from whom the family has evolved into its current 5th generation.
