Hi there,
I have looked at the records that i have access to and can only find a record for a John Murray Laing that died in 1964 and is buried in Stellawood cemetery aged 56. I then looked in Naairs and see that his death notice reference states John Murray Laing b in Scotland, Surviving spouse May Laing b Poulter.
Unfortunately I could find nothing on any of the other members of the family
You could apply for his death notice - see sticky at the top of this board - and you may find out more.
Please be aware that this forum has a restriction for searching for living members so be cautious what you post.
Have a lovely day:)
Ruth
PS Although they disembarked in Durban, they may have been en route inland... Free State, Transvaal or even Rhodesia.
