My great grandfather was born in Budapest in 1913. I’m passing through the city for a day and I’d like to see the neighborhood my family lived in for a few hundred years. They were Jewish and somewhat well off, but left around 1920. Not sure what any of this (birth certificate) says, translate doesn’t really work on the cursive and the text is obviously a bit damaged in a few places. Any help would be really great! I believe the most damaged part is the house address.
