Do you have any sources on this? I don't know for a fact that Leo Zagami is a trustworthy source or that he is even a Mason. So if he is the best source you have then you have to do better than that.

Historical sources are better, where many historians reach a consensus on a chain of events. Such as it's known fact that Freemasons were some of the founders of the United States based on the consensus of historians. Rumors of meetings behind closed doors and unknown individuals like Leo Zagami aren't what I considered to be good sources of evidence.
