I'm cutting her off, and will add MP'd N.N.' as Contessa's parents. Actually, I'm even more puzzled by the following profile on her path higher up...22 Generations to Yehoshua ben Zimri - earliest recorded Rashi's ancestor.
I suspect that if this were legitimate, we'd already seen a full line of 22 generations instead of a single wrap-up.
Malka Mysels and Private User -- If you look at Private User's comments on Randy's various posts about this line, the line's connection to the Horowitz line has no basis in fact.
The two of you do most of the work in rabbinical families. Can you handle this? Thanks.
