הגאון רבי עקיבא הכהן כ"ץ, מאובן - Was indeed his father-in-law was Rabbi Avraham Katzenelnbogen of Uban?

Jacobi states that his father-in-law may have been Avraham K'bogen: Jacobi Papers: Vol. 2, p. 123, 19.1.

I further conjecture that Avraham K'bogen may have been the son of Rabbi Moshe whose other son Yitzhak ben Moshe, [of Ellenbogen] died in Prague.

Thank you very much Adam, I don't have the Jacobi Paper, but as I wrote before, according to Naftali Wakstein there is a mistake in Geni and in some books, because according to him, Rabbi Yitzchak Katz - the son-in-law of the Maharal from Prague was not a descendant of Rabbi Akiva Katz....
I hope that in the next article he will write about it and then we will be wiser.

So my grandfather is not a descendant of Rabbi Akiva Katz, but I am a descendant of him through my grandmother

If you have information regarding the continuity of the family tree, I would appreciate it if you would add it

I have tried many times to find the continuity of the family tree from

Rabbi Akiva Hakohen Katz, ABD Saloniki (Alter of Salonika)
And so on, but I couldn't find any information

Having taken another look just now, I agree that I have seen no evidence that the father of Yitzhak ben Moshe, [of Ellenbogen] is a Moshe. However since he has sons Meir and Moshe, from naming theory, the father may have been a Moshe or a Meir.

It is still possible that the fil of Akiva of Ofen was a K'bogen, and further that he was the brother of Yitzhak ben Moshe, [of Ellenbogen].

The first generations after Akiva of Ofen are tricky and I look forward to further explanations.

In the Encyclopedia Judaica the Akiva article cites as a source: B. Mandl, in: Mult és Jövő, 25 (1935), 316; MHJ, 2 (1937), 537–8. A researcher in Hungary was able to obtain a copy of this source which reports a primary document signed by Akiva where he himself writes his name as Akiva b. Menachem HaCohen. The researcher went on to obtain a copy of the document, which reads Akiva b. Menachem HaCohen, as reported by Mandl. I have posted the documents on GENI (https://www.geni.com/photo/view?photo_id=6000000205941795887 and https://www.geni.com/photo/view?photo_id=6000000205944248905 and https://www.geni.com/photo/view?photo_id=6000000205944351880); these cannot be attached to Akiva’s profile directly due to blockage.

If so, is it possible to ask a curator to open a profile of Menachem HaCohen as the father of

Rabbi Akiva Hakohen Katz, ABD Saloniki (Alter of Salonika)

Maybe Randy Schoenberg will address.

Yehuda ben Yitzhak Abravanel is your 18th great grandfather.

Elazar ibn Shmuel al-Hurga, Alluf al-Andalus & Resh Kallah is your 35th great grandfather.

I've uploaded HaGaon Rabbi Akiva HaCohen Katz, of Ofen's high-resolution signature here from microfilm (the original was sadly destroyed in WW2): https://www.geni.com/photo/view/6000000197770991827?photo_id=600000...

It would be great to contribute to Akiva of Ofen's profile directly for those of us researching him in physical archives, as currently it is impossible to even tag him on Geni.

Any chance Akiva of Ofen's profile, which has been locked for 11+ years now, will be available for researchers again, Yigal Burstein ?
