According to the Geni tree, Saul Wahl Katzenellenbogen (1 day King) is shown as the son of Rabbi Shmuel Yehuda Katzenellenbogen, MaHaShiks, MaHaRaM son #1 and Abigail Ogla Katzenellenbogen, the latter being the daughter of Rabbi Mordechai Jaffe, Ba׳al "Halevushim". This seems like an obvious error. The birth dates of Saul Wahl Katzenellenbogen (1 day King) and Rabbi Mordechai Jaffe, Ba׳al "Halevushim" are just 11 years apart!
One plausible solution is that a son of Saul Wahl Katzenellenbogen (1 day King), Shmuel Yehuda Katzenellenbogen who had the same name as his paternal grandfather Rabbi Shmuel Yehuda Katzenellenbogen, MaHaShiks, MaHaRaM son #1 was the son in law of Rabbi Mordechai Jaffe, Ba׳al "Halevushim". But again that doesn't fit with the current information on Geni, where wife, Shmuel Yehuda Katzenellenbogen is given as the daughter of Rabbi Moses ben Israel Isserles, "RaMA"?
Can someone clarify all this?
