On my family tree, I have a woman whose name is Regina Herz.
While researching her name, I found this information
The dates are perfect.
My ancestor (whose family changed their name to Morningstar … with think it was originally Illava or Pivany) was born in Szered in 1798. He was a doctor. My father always said he was „doctor to the children of a duke or a prince).
I see from the list of Vienna births that Regina Herz was a teacher. Maybe she taught the Esterhazy family?
The family came to America around 1850 while fleeing the revolution.
I keep track of my family here: tomer.tribalpages.com
If you could make all this information public, perhaps I will find someone who knows something about that area that was called Mattersdorf.
PS My ancestors spoke German
