How can I find traces of my great uncle Julius Zabransky?

Request for assistance on information about my great uncle Забранский Юлиус (Zabransky Julius) - https://ru.openlist.wiki/%D0%9...%81_(1913)

I am searching for more information on Julius Zabransky’s life in Leningrad from March 1934 to July 1936 (arrested by NKVD 4 May 1935). I have obtained Austrian files on his deportation from DÖW (https://www.doew.at/), and I am looking for any documentation on his arrival in USSR as political emigrant 6 March 1934 until his arrest, deporation and rehabilitation. Not all of the biographical information from DÖW and ru.openlist.wiki has been made available to me. Here, references are made to ÖStA and GARF (Государственный архив Российской Федерации (ГАРФ)). I am reaching out to you in order to locate the latter, and to identify other sources.

In the documents obtained from DÖW there is evidence Julius Zabransky got married and had a son about the same date he was arrested. Can you help me locate more information on this marriage and his son – or recommend where to locate such information? I am enclosing the files from DÖW, where page two identifies his wife as Nina Zabransky, born Busch, living in Leningrad 9, ul.Komsomola 13, Qu.7 and a son born 6 May 1935. I am also searching for information about this wife and child, as I have not yet found anything else in Austria.


Julius Zabransky was born in Wien, Austria 28.3.1913 and died in Wien 7.2.1992
