Hi, 

I'm a descendant of Yehudis Brunner nee Fabula. She was the daughter of Aron (Leib) Fabula. 

According to researcher Balazs Deri, this is the same family as the one you are looking for. 

Aron Fabula had a son Samuel, who had a son Josef who married Fanny Rebekka Friedman, their daughter Serena married Josef Schwartz .

Unfortunately, I don't have any information on the Fabula family, only what Balazs Deri posted on geni.com. I would love to find out more information if you have.
