I'd like to start cleaning up the top of the Horowitz tree. What we have now is an amalgamation of various attempts, but with few sources and lots of potential mistakes.
I have added a bunch of the critical literature on the family to the Media tab for Rabbi Yeshaya ben Moshe Asher HaLevi, The 1st Horowitz under Documents, as well as to the Jewish Families from Prague project at https://www.geni.com/projects/Jewish-Families-from-Prague/documents...
What I am going to do is disconnect and identify in this discussion any profiles for which we have no good source. We can then put them back when we find a source, or put them in the correct place, or delete them.
Some of the main sources for this work will be:
Wachstein, Wer sind die Prager Munk im 16 Jahrhundert?
https://www.geni.com/documents/view?doc_id=6000000050515527927
Hermann, Steuerregister der Prager Juden aus dem Jahr 1540

Putik, Causes and Consequences of Prague Rabbi Revolution in 1579
https://www.geni.com/documents/view?doc_id=6000000172925239929
Also useful will be
Hock, Die Familien Prags
https://www.geni.com/documents/view?doc_id=6000000078560646925
Lieben, Gal-Ed
https://www.geni.com/documents/view?doc_id=6000000078560073461
And the Popper cemetery notebooks on the website of the Jewish Museum Prague
https://collections.jewishmuseum.cz/index.php/Search/Index?search=J...
I also have in book form
Muneles, Ketovot
https://catalog.hathitrust.org/Record/002454566
Jacobi Papers, vol. II, Horowitz chapter
https://www.iijg.org/jacobi-series/
Most of the genealogies that people have relied on are using some, but not all, of these sources, so it is high time that we did some work and consolidated what we know and correct some of the mistakes. Muneles himself had planned to publish a new version of his work, but was not able to complete it.
Feel free to ask questions here in this discussion.
