Irma Schindler (Spitzer) - Irma Spitzer

If you look in her fathers Media section, you will find a picture of the house. Its right at the marketplace and still exists. The Adress is the Scherschnittgasse, the name likely changed.

Thanks for this information. I am trying to get hold of Irma's and her husband Julius' birth certificates. The Czech researchers state that those records were destroyed by Nazis. But the family applied for Liechenstein nationality on April 12, 1932. I am now trying to get a copy of their documents through Liechenstein archives.
I would also like to know if they ever became Germans (proof not heresay) and perhaps lost it when the Nazis stripped Jews of their German nationality circa 1933..

They became German and than Liechtenstein. Julius wanted to have both citycenship but this was not possible, so he lost the german nationality.
