Where were British refugee children sent during WW2?

Brittish refugee children were spread out from the main cities to the countryside or very secluded rural areas. This was to prevent the next generation suffering at the hands of the Nazi's during the time of the Blitz and other air raid attacks. This was put in place once the Germans had began bombing Britain, and it was thought a better fate for these children to be separated from their parents and sent somewhere safe.
Unfortunately, most of these children never got to see their families again, and were brought up in a new home, new family and in many cases, with a new name. Where time had taken their history and family remnants forever.
