I tried to answer you in the discussion itself, for a reason I do not understand, I could not, so I decided to open a follow-up discussion to the discussion you raised on the subject:
The rabbinic literature is very divided as to the identity of the parents of
Rbzn. Dina Katz Heschel
And also about the identity of her children from her husband
Rabbi Abraham Joshua Heschel, Head, Cracow Yeshiva
Because I'm a descendant of
Rabbi Issachar Berish Babad
I tried to find solid information about his mother's identity, I consulted with people who understand rabbinical families, most of them (and also most of the rabbinic literature) claim that she was:
Hesya Miriam Heschel
, as it now appears in geni
But some (and also some of the rabbinic literature) strongly claim that his mother (who was also the mother of his brother Rabbi Shaul) is Dina (Katzenelnbogen ????)
When I realized that there is no decision on the subject, and no source has solid evidence, I decided to leave the research in this branch and concentrate on research in another branh
In conclusion:
I am afraid that no one has and will not have solid and reliable information on the subject, and everything that is done in this branch, will never have conclusive proof that it is the right and true thing...
The identity of her parents should also be checked and consider whether she was indeed from the Katzenelnbogen family, but this is one of the cases where the information about the identity of any person is so divided among the many books, and people dealing with rabbinical families
