Okay. So, here's the interesting stuff about Eugenjusz Rozenblum (and all his variations).
I worked backwards from the testimony that the USC Shoah Foundation recorded with Dr. Eugene Miller. He identified himself as Eugeniusz Rozenblum of the Lodz ghetto, born October 16, 1923 in Merkine, Lithuania. Based on that, it is pretty clear that there was at least one error entering data or in the original ghetto documents. Cross-referencing the street addresses and birth dates, I concluded that Emgenjusz, Eugenjusz and Eugeniusz were all the same person (and male, too).
Note: As it turns out, the USHMM has an "ID card" biography for Eugeniusz that lists his birth place as Lodz. However, this is a secondary source. Both his postwar testimony and Dachau camp records show him as being born in Merkine/Merkinia; as primary sources, I view them as more reliable.
There is one date notation (August 2, 1943) which is unclear (ie, was it a change of address or does it indicate another event of some sort?). However, it does appear that he moved to Hamburgerstrasse 41 on February 2, 1944. Even more interesting, it appears that he was living alone at that address by April 1, 1944 (HAJM FUR EINSAM AUF MA). The upshot of all this is that he was still alive and living in the ghetto by Spring 1944.
There is a Worker ID Card rich with data on Eugeniusz. It confirms his birth date as October 16, 1923 and the addresses listed in the Lodz Ghetto Inhabitants database and is stamped TRANSPORT indicating he was deported from the ghetto. Unfortunately, the date is not fully legible. It appears to indicate that he was deported on 20/xx/1944. Was it at the time of ghetto liquidation (ie, August 20, 1944) or earlier?
Not surprisingly, the USHMM summary notes on Eugene Miller's testimony confirm that he worked in the ghetto Fire Department (though he claims living at a different address than the ones listed in the ghetto documents): "He explains that those who went to school got soup in addition to their bread; tells that his address in the ghetto was Brunenstrasse 16; explains he continued his high school education until September of 1941; tells that after school closed he was assigned to the labor department at 17 or 18 years old; remembers he worked in economic department; explains that the teachers at the school were from various Jewish schools around Poland; remembers that Professor Silverbogen became principal of this school; says that after school ended he did whatever they asked him to do and probably worked around 10 hours a day; explains the place he worked, Wirtshaftam, did administrative work and was created by Rumkofsky; explains he was reassigned to work in court in 1942 mostly dealing with thefts; remembers there were no phones so kids would run notes around the ghetto; explains his job was easy and his cousin had an accounting job for the Wirtshaftam; answers that his father in this time did not work but died slowly of hunger; explains a loaf of bread in 1942 cost over $100-150; tells you had to work to get stamps for food but his father got stamps for being sick; recalls that the German Jews in the ghetto were not treated well and many committed suicide; tells in may 1943 he was transferred to the fire department; details job in the fire department as preventative work; gives details of the Arbeitsresort as a manufacturing or minor factory area; tells every day they were assigned different jobs."
Checking the databases for evidence of Eugeniusz's parents, I cross-referenced with info from the USC Shoah Foundation catalogue, which lists his parents as being Mordechai and Ida. In the Lodz Ghetto database, they are listed as living at Brunnenstrasse 16 38 -- the address which Eugene Miller provided in his testimony to USHMM. So, this must be where they lived prior to the addresses recorded for Eugeniusz in the Lodz ghetto inhabitants database (or there is some other explanation for the discrepancy?)! BTW - The date of death given for Eugeniusz's father was July 30/31, 1942.
Eugenjusz is recorded as being a "Schutzhaftling" or protective custody prisoner and a Polish Jew. His "place of origin" is listed as Lodz and his former address as "Marutowiczs 41." I find this interesting since he had lived at Hamburgerstrasse 41 previously. This doesn't appear to be the original Polish name for the street. So, what is it?
He eventually emigrated to the United States and was the sole survivor of the 70 people in his extended family according to the his ID card biography on the USHMM website.
