Maybe this information may help someone or maybe someone can help me fill in the missing links.
Our Family also has it's origins in Germany, about four generations back from myself. We were born in South Africa. I am the youngest of four Preller brothers born to Beverley Anthony Preller, who was born in Fishhoek on 23 October 1927 and died in Bloemfontein on 28 March 1975. My Mother is Alice Vos and is still alive and well.
We are currently searching for relatives of my Grandfather, Roland Preller who was married to Antoinette Friedrich. They had two daughters and two sons, the youngest son was my father. The other sons name was Patrick. The daughters were Rolene and Beryll.
