JInxy, my gradfathers family too were caputred, my grandad was made to work on a farm he didnt see his family again he presumed they had been killed,
he came to the UK in 1948, he married my nan in 1955 he later found out that his parents were still alive and sent wedding photos but heard nothing back.
he did also have a niece, she came to the UK looking for him in the 90's
he received her letter the day she was due to leave back to the Ukraine and aftera rush up to the airport i belive there was a reunion but they did not keep in contact.
