So... are you calling Dr. Hahn a liar? His original account and the secondary account seem to mesh together, do they not? (Beyond that: given the splintering of the Presbyterians, is it really surprising that they've spawned numerous private places of worship which still consider themselves Presbyterian? Unless you're willing to consider every last Presbyterian "fragment" to be illegitimate, I'm not sure how this furthers your case.)
Uh, no. Having witnessed the process, that's not really how it works.
