The supplementary records were used primarily to search for relatives of unaccompanied children. These were children who had been found without parents or other family members. However, UNRRA and later IRO employees also filled out the records for other people who, on account of illness or trauma, for example, could not say exactly who they were. To distinguish these two groups, the UNRRA and IRO employees were supposed to write “unaccompanied child” on the upper line on the forms for children. If the child’s identity was also unclear, “unidentified unaccompanied child” was added. This could be the case for children who had been taken from their parents by the Nazis – particularly in Poland – in order to be given up for adoption in Germany.
