Can you document this? I've always understood that all Orthodox in North America were under Russian jurisdiction when St. Tikhon was Archbishop of Alaska and All-North America.
Aside from the records of my parish, which aren't online, try this link:

Scroll down about halfway.
An even better bet is this:

That was my understanding aslo Kolo (The whole reason old Russian orthodox church says Russian Greek Orthodox Church) or some such...
Do you think the EP would have been able to make the moves he did had the Russian church not been compromised?
