Roelien Oeschger, Robert Johannes Peacock (brother), Robert Johannes Peacock (father), Robert Johannes Peacock (grandfather). We were all born in South Africa as far as I know.We live in Centurion, Gauteng. I know my great grandfather had lots of children, and that he had 2 wifes. Does not know much about grandfather as he died when my father was 8 years old, and because of depression years, children was in a orphanage. Does anyone know if this RJP Oeschger goes back even further?
