I believe it is conclusive, the U of Washington and Corsi to the contrary notwithstanding, that the first hard evidence of Stanley Ann being at Washington in the fall of 1961 is on September 19, not August 19 which would open a reasonable gap between the birth date and the appearance date.
I also think it is reasonable to suspect that if there was a marriage on the the rest of the record we have before us, it occurred in Kenya where it would not have constituted bigamy nor have otherwise been socially unacceptable.
I think the material about MX and the rest of the New York story is pure speculation until someone comes up with some single piece of evidence to connect it to Zero.
