Hi
Welcome to Rootschat

Pauline s idea is a good one, local archives. There is a account of 3 men (Aged24 and 25) from Bristol who sadly died in February 1962 in a car crash in Bristol.
Not really fair to mention their names on the forum but did you know your fathers name, perhaps you could post initials?
There could be more candidates though of course

There is also an account of a car that crashed down Avon Gorge with 4 deaths but that was in Sep 1963
