About Johanna Kron (Kunst)
Her husband Philipp Pinchas died in Brno in 1874, so she possibly decided to move to Vienna to be close to her children (all resided in Vienna except one, David, who lived in Brno).
They probably moved to Brno from Gewitsch, maybe after the 1869 fire, which destroyed the main part of the Jewish quarter, and made many Jews leave the town .
She is first registered in Vienna (in the Lehmann's Allgemeiner Wohnungs-Anzeiger) in 1877, residing on Schulerstrasse 17. She possibly moved to one of the family houses in Baden b. Wien, where she died 7 years later.
