Several of the Frank sisters' school friends had survived, as had the extended families of Otto and Edith Frank, as they had fled Germany during the mid-1930s, with individual family members settling in Switzerland, the United Kingdom, and the United States.
Mange af Frank-søstrenes skolevenner overlevede også, ligesom medlemmer af Otto og Edith Franks familier, der var flygtet fra Tyskland i midten af 1930'erne for at slå sig ned i Schweiz, Storbritannien, England og USA.
