Your post triggered a long-dormant memory
In the 1970s my mum and dad told our family (4 kids) that we were going to have to put our uncle's family up as they were arriving from Rhodesia at short notice. We were all pissed off - the 3 bedroom council house was already cramped with our family and grandma and where they were coming from and why at such short notice never crossed my mind to ask.
Turned out that my uncle was one of the senior officers (deputy warden I think) at Salisbury Central Prison and the family had to flee Rhodesia suddenly one day - leaving everything behind.
He never mentioned anything, but later when I realised his role I also wondered just what he had seen or had been responsible for
