My great grandfather Hermann (b. 1866 in Alexandria/Egypt) lived in Vienna on and off. His father's name was Israel, but I have no clue where he came from. I believe it was Vienna. Hermann had at least a sister, who lived in Villach for a while and took care of his three young children, after his wife Eugenie died at a young age. They got married in Vienna. She was born in Trieste however
and grew up in Gorizia and Trieste.
I would like to find out her name, but frankly, don't know where to start.
Wondering if anybody could help out.
