Though Rampolla was blocked from the papacy, Della Chiesa (Benedict XV), Pacelli (Pius XII), Roncalli (John XXIII), Montini (Paul VI), and Pietro Gasparri (Cardinal Secretary of State 1914-1930) were proteges of Rampolla. The banking families of Pacelli and Montini were also connected to the Rothschilds.  Instead of the usual school and seminary training, from childhood both Pacelli and Montini were tutored under the personal direction of Rampolla. They were so tutored until their last two years before ordination.

For details, see:

The Undermining of the Catholic Church
by Mary Ball Martinez (requiescat in pace), who was for decades a Vatican journalist and insider, ASIN: B0006EZHKS, https://www.amazon.com/gp/product/B0006EZHKS/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0006EZHKS&linkCode=as2&tag=httpwwwchanco-20 />

Card Rampolla was not "blocked" by anyone. The "veto" was abolished by Pius IX( although he forgot to attach the penalty of ex-communication to anyone who might try it). On the first vote after the alleged "veto" Rampolla did not lose a single vote-- showing that the cardinals were aware the veto was Null. While Della Cheisa was close to Rampolla in the early days, the latter soon figured out that he had become Modernist( I still have lingering doubts as to the legality of Della Chiesa election). This is the first I have heard of any connection between Rampolla & Roncalli or Montini. Lets remember that it is Della Chiesa & Not Rampolla that ( like Montini to Milan later by Pius XII ) is " exiled" to Bolonga by Pius X.

I am not aware of any connection between Pacelli & Rothschild.

Mrs Martinez book is very inaccurate.
