The travel manifest for 1958 has him travelling with a Mrs Muriel Powers and children Janet(1945).John(1946) and Andrew(1955),the gap suggestive of a different mother?
Andrew's mmn is Payne and there is a 1950 marriage of George C Powers to Muriel Payne in Essex
This seems to be replicated as Muriel Dearmer.
Have to go now,back later
