This Chapter is currently shown on the project page as being descendants of Unknown Profile
But his children as currently shown on Geni don't appear in Chapter IV of the book.
There is some correlation of the 10 children of Rabbi Yona Frankel Teomim, the "Kikayon DeYonah" with the 7 children G6.1 to G6.7 shown in Chapter 4 on pages 243 to 267 of the book.
I would suggest changing the progenitor of Chapter IV on the project page, and taking a very close look at the children of both R Jonah profiles on Geni to see which really belong there and which don't. Easiest way to do this may be through curator notes.
I found the "missing" child of Rabbi Yona Frankel Teomim, the "Kikayon DeYonah"
So he now has 11 children on Geni. I ordered their birth order on Geni so that the first 7 correspond with Ch IV of the book. The next 4 come from I know not where.
The 6 children of Unknown Profile also come from I know not where.
Thanks Randy for changing the project page. I tried to edit it - but you and I were editing at the same time and my changes got overwritten.
I wouldn't like to merge the two Jonahs - I suspect that the second Jonah's children belong elsewhere. It is possible that merges have brought in all kinds of extra descendants into the Geni tree who do not belong as Ktz. descendants.
