I just wondered if you've had any luck tracing 'Mick' Crozier ? I am also trying to trace a Mick or Michael Crozier who was probably Irish. Again I do not know if Mick was his given name or a nickname. The Mick I am searching for ran a pub in Dagenham in the 1970s. I think he would have been too young to be a publican in the 1950s but it may be a relative of his that you are searching for? Seems a bit of a coincidence!
