Ms, Yiftach bedoro keShmuel bedoro. Read Rav Kook’s hesped on Herzl, “Misped b’Yerushalayim” printed in “Maamarei HaRaya”.
Toi,
1. Only one of Herzl’s children was baptized. He committed suicide, apparently as a result of emotional problems, after leaving a note doing teshuva gemura on his apostasy. BTW, Rabbenu Gershom also had a son who was a meshumad (I presume to Natzrut although it is not specified). This is brought down in the Hagahot Oshri on Moed Katan Perek 3. So this proves nothing about the parents.
2.How do explain the talmudic principles “naval beresut haTora” .
