The responsible officials knew that some people might provide imprecise information about their name, birthdate, birthplace and nationality. For this reason, they added an “evidence of verification” field to the supplementary record. If the information had been verified (by an identity card, for example), they noted where the verification had come from. On all of the records examined thus far, however, this field is either blank or the word “none” is written. It was especially important to clarify a person’s nationality, because if no relatives could be found, children would be returned to their respective countries of origin, where they would initially be cared for in children’s homes while the search for relatives continued.
