de Beer Genealogy and de Beer Family History Information

My name is Stephan de Beer, born in South Africa, I have managed to build my mothers family tree see http://www.myheritage.com/site-family-tree-18887961/jansen-van-vuur... and am now trying to unravel my father's. My father was born Stephanus Johannes de Beer (deceased) had a brother Diederick de Beer (living) they both came from Springs South Africa. I understand their father came from Colesberg in Cape Province South africa. As I have researched my mother's to the initial van Vuuren that came from a town called Vuren in Holland I wish to do same with my famiy in South Africa through to Europe - either Holland or Germany. if you can help please make contact debeer.066@gmail.com
