You opened a discussion and asked for a reference to your words...because I am a descendant of both of them, I looked into the matter.
If Dr. Wonder did not make a mistake in his understanding of the book "She'erit Yosef", and did not take things out of context, then the things written there are as I wrote.
In my opinion, (assuming that Dr. Wonder understood what he read well), there is no possibility that Rabbi Yosef Katz did not know who his aunts were, but I will let the curators decide what information is acceptable to them, and I will accept their decisions
