Every name and title is referenced to Italian encyclopedias and the Italian Version of Wikipedia Everything else is in black and white in Cardinal Antonio Samores Lo Stato Landi  referenced from the Vatican archives and the ADLP Library IF you are questioning The Cardinal and The Doria Pamphili Library good luck It is all cross referenced to multiple sources st If you cant read Italian use Goole translate same for Latin Every Vatican source is referenced in Samores book from  books documents from the Secret Vatican Archives non est argumentum ad hominem  Oh just in case Stop attacking the messenger Do your job and read the reference material Samores book is not questioned by anyone it is referenced from over a hundred Vatican sources Find someone who can read Italian and Latin Encyclopedia Britannica has accepted these materials for and article to be published in next edition They did there homework     References to Wikipedia English Italian or any other language are not considered reliable sources because as we see anyone can edit and change the information We need better references than that The other references are valid and Im not questioning them What I am questioning is the need for an article on the Landi State separate from the article on the House of Landi which already covers the topic of the Landi State in as much detail as is needed given the obscurity of the sources As for accusations that I have attacked the messenger please point out what I have said that is any way an ad hominem argument
