The only trace of Rozenblums family we have been able to find was fairly vague information to our eyes, but maybe you could make use of it. There was a Szlama Rozenblum registered as a survivor in the Register of Jewish Survivors II pg 225 record number 52838. There was also Rwyka Rozenblum registered in the same book on the same page under the record number 52831. Both file numbers are identical, 10/DSC00036.JPG
