Rabbi Benjamin Wolf Spira - Research Note

I see Jacobi is an author of a book. I checked my list and I don't have that book, so I can't compare.

Jacobi was published in 2019 so not widely available. The Papers are the work of 50 years of studious comparisons of all, and I mean all, the available sources, including Wachstein, Wunder, Kaufmann, Zunz, Friedman, etc. and many private family trees as well. I'm just letting you know what is in there. What you do is up to you.....

Can you please give the full cite, so I can try and get a copy?

Do you mean this?

Yes those are the published papers. You can also check with Worldcat if there is a library near you with a copy.

I am finally going through The Jacobi Papers. Assuming Jacobi is right, there are larger problems with the Spira tree, namely that Jechiel-Michel's father was Nathan b. David Spira, not Yoseph Yerushalmi-Spira. This would be quite exciting for me personally as it would take me back five generations. But it would mean that a lot of information here on Geni is flat wrong.

I saw that today and in the last few days I was disconnected from my ancestors of the Shapira family, and connected to other ancestors from this family...

It is interesting, because when I was working on this branch (Shapira-Yerushalmi), I did not rely only on Dr. Wonder, but I cross-referenced information between various rabbinic sources

Are the changes made from The Jacobi Papers? And if so, does he indicate which sources he relies on?

Hi Haim.

The Paul Jacobi papers have a different ancestry for Yechiel Spira. Jacobi says Yechiel's father was Nathan son of David. This is from the Spira tree in The Jacobi Papers volume 4. This is causing some changes with the tree above Yechiel.

Jacobi doesn't really have a source for this as he says that Nathan's name comes from his son's epitaph, but there is not (to my knowledge) an epitaph in Prague that says Yechiel ben Nathan. Jacobi's sources for Yechiel all point to his being Benjamin Wolf's father, which no one disputes.

Randy wants me to start a public discussion where I will put some of the information I've found and that others have said.

Where did you get the entry 643 about Yechiel Jerusalem. It cites Weitz, but I don't know where it was from.

I responded to you in another discussion that you started, but I will summarize what I wrote
:
Rabbi Mordechai Weitz is considered one of the very most reliable rabbinic sources, and therefore the things he wrote are copied by many people...and when I researched the Shapira-Yerushami family I relied on the things he wrote

I know about Jacobi, unfortunately, I don't know what sources he relies on
