The difference is that there is nothing to corroborate this alleged Kenyan BC.
On the other hand, we have the word of the Hawaii Department of Public health plus two birth announcements to corroborate the facts attested to by the Hawaiian COLB.
Furthermore, the idea that an 8 months pregnant woman would travel half way around the world in 1961, to a third world country, in a journey likely lasting several days and multiple primitive modes of transportation, for no apparent reason, is just plain looney. If you can't see that, then you are either insane or willfully blind.
You are becoming the King of the Strawman.
Who's to say she was 8 months along when she traveled, if she traveled? Her whereabouts are unknown from at least the end of the fall semester at U of HI, that would be the last part of January, not early July. She would have only been about 3 months along, when most women aren't even "showing" and generally before "quicking", especially in a first pregnancy.
