Bernhard Ignatz Kohn - House of Kohn in Vienna

Hello, I have bought an apartment in the house where Salomon Kohn and Henriette lived with their children (Ignatz ...) in Vienna. I have also a photograph of the original house, which was rebuild and looks different now. I would like to get in contact with any persons who know more about this nice family. Please do not hesitate to contact me: Dr. Nestor Kapusta, 1170 Vienna, Austria (nestor.kapusta@gmail.com)
