I have been attempting to research my grandfather, Jozef Lewinksi who, via the Polish Resettlent Corps in the UK, settled in the Doncaster area of Yorkshire after being discharged from the army, as a private. I think his army number was 30028254. I think he enlisted to join the allied forces in 1941. He had an alien registration card in the UK ‘KRD 7489858’. He was born 02 April 1913. I have no further information about his polish/ukranian/Lithuanian heritage or family and would like to find out more. Can any help?
