Jewishgen's record of her husband's death verifies those details

The suggested alternatives appear to be Germanic fabrications of exactly the same names that are presented without any documentary support

NO and Yes
There is only Jewishgen evidence to confirm her husband was Jeno son of Katalin.

I found no record to confirm that Jeno's mother Katalin was also known as "Katherine Karlota"

There is no mention of a Eugen, Marianna is just shown with her husband Jeno, who was the same husband she married when just 20 and still had when she died
