Hi, 10th August 2020
As you mentioned Hungary
I remember a BLITZ ANIKO/ Aniko Blitz being in the Budapest Jewish Orphanage--at Delibab utca 35 between 1964-1968
I left Budapest in 1970--so I do not know if Aniko Blitz remained in Budapest or not?
I wonder, was Aniko an 'orphan' or an --emotionally and physically --abandoned child? sadly, I do not know.
If you are interested, I can try to send some e-mails to Budapest in case my former school mates remember her./Aniko BLITZ.
Wishing you Mazel and Brocho in your research
