My great-great grandmother died in Pittsburgh in 1929. On her death certificate, her parents were listed as Anton Fürst and Anna Dobrava, both born in Vienna likely around the 1850s. I can't find anything regarding Anna (admittedly, I may have read her last name wrong, the handwriting's a bit loose with the V's, R's and U's), so I'm trying to look for Anton instead. The problem is that looking for a specific Fürst in Austria is like looking for a needle in a haystack.
I know I have next to nothing to go on, but any point in the right direction would help. :)
