And this:
In the Roman Catholic Church, protonotary apostolic (PA, Latin protonotarius apostolicus) is the title for a member of the highest non-episcopal college of prelates in the Roman Curia or, outside Rome, an honorary prelate on whom the Pope has conferred this title and its special privileges. An example is Prince Georg of Bavaria (1880-1943) who became in 1926 Protonotary by papal decree.

So it could also be someone outside the church. Interesting that in the above example it is a Prince which implies that it could also be a member of a royal family - most likely in Europe. Most of them are involved in this shit (pedophilia/satanic rituals, etc).
