There's a discrepancy who Katalin's mother is, whether it is Fani Quittner or Zsófia Himmler. Many sources don't even mention her mother's given name, only "Quittner". Look at the father's profile to see what I mean: https://www.familysearch.org/tree/person/details/GRV5-1M7
Fani Quittner (born 1845) was too young to have given birth to Katalin in 1853. Katalin's (half?) siblings were born close together in time but a decade after Katalin's birth. I am assuming that Katalin's mother is Zsófia Himmler, which could have either been Samuel's first marriage or an illegitimate daughter.
I couldn't find any information about Samuel Quittner's or Zsófia Himmler's age. There's just one record that connects Katalin Quittner to Zsófia Himmler.
