CasB on Family Tree Circles

I am trying to find anything at all about my father's family. I know his mother was Daisy May Upsall and his father James Charles Sim. He had one sister and three brothers; May, Arthur, William and Albert. Any and all help would be greatly appreciated.

I am trying to find the history of my father-in-law's family but unfortunately only have his name, Edgar Desmond Blundell, who died in Durban, South Africa, on 20th August, 2000. Any and all information would be most gratefully received.
