I don't think they have middle names, but I don't know for sure. I do know that Harold died some time in the 1980s. I have tried looking at some school lists in Friends reunited,but have had no luck. I'm not sure which schools are the nearest to Howick either.
I really do appreciate your help!
Thanks again, Gail

I think one of the boys may have been born in Kenya or Tanganyika if that could help at all.
