I am trying to trace any information about my great grand father. He was from England and was a doctor. He came out to South Africa in the 1920`s and died of a virus after about two months. He was married to a woman of the name of Diasy May and had two daughters Dulcie and Sheila Nance , who was my grandmother. If anyone has any information I would be most grateful.
Thankyou
