I unlocked all of the stages so I could use the databases in all of them. Once I got to stage 5 I opened the post-war database and put in Herszenberg. I didn't find any of my Herszenbergs but I did find a new database in one of the many Herszenberg names I clicked on. It's called data.jewishgen.org. I put in the Herszenberg surename and it came up with a lot of databases. The one that really caught my eye was the "Lotz Ghetto List" which had 105 names in it. So I opened it up and saw - 4 names from the top - Abram Herszenberg who I was looking for, since you wanted me to find more on him. I confirmed his DOB to be 21/12/1898 and he had an "address" of Aleja 1 Maja 121. The reason for the quotes was that was what the database listed. Because he had a "Ghetto House" of Hamburger Strasse 21 Flat 76, and and Occupation of a "Manipulant". Everywhere I searched a Manipulat was a manipulator, so I don't really understand what his occupation was, what did he manipulate? I also confirmed that Gilta Herszenberg is the real one and the she does not have a twin sister named Guta. Gilta's DOB is 08/08/1924, has an address of Wald Strasse 23, a Ghetto House of Hamburger Strasse 21 Flat 76 and an Occupation of Schuelerin. Since she has an Occupation of Schuelerin does that mean she would be on the list? I looked at the list on this site and she wasn't on it, but there was a lot more names than what are on the site. I also confirmed Luba's correct birthday to be 31/12/1925, so I deleted the wrong one. She also had the same address and Ghetto House as her mother and sister. Does the address versus the Ghetto House mean anything? it had a space for a change of address and it was blank for the whole family. Could one of the addresses be their address before they were moved to the Ghetto? I don't really understand the father's "address" as Aleja 1 Maja 121, I couldn't find it on anything else. I apologize if I am scatter-brained in the comment, I'm pretty excited at this find.
We found two addresses for Luba. Wald 23 1 and Hamburger 21 76. We can't add them since we do not have a date. We also found a possible mother, father and two sisters. The two sisters are twins because they both have the same birthday August 6th 1924 and have different names. The mother and the father's birthdays are in the appropriate age to be parents. Since they all had the same address and change of address we are very sure that they are all related. I could not find a place to add siblings.
