We have to keep in mind that the regulation mentioned on the bottom of that item didn't come into force until the early eighties iirc. Maybe Madelyn (per grandmother) attempted, unsuccessfully or successfully...to obtain a COLB on the strength of it.
And 'birthplace Kenya' might just be there because it doesn't point to where he was really born. In other words, what we are looking at could be a report of an out-of-state birth, of a child whose mother and father we have no idea who they were.
“We’ve been led to believe this document is a fake, but if it isn’t, if what we see here was the initial attempt to lodge an application for a birth certificate which might give rise to a birth announcement in the Honolulu papers, then this is the first time he’s shown to have a birth year of 1936.”
I agree that this forgery is a good approximation of what such a filing would look like, but the talented forger knew that.
The forger neglected to remove stray marks in block 19a that were from signatures on the real BC that was used as a base onto which forged signatures were cut and pasted. On the web there are images of the original and the stray marks in 19a match perfectly.
Note that Madelyn’s name is misspelled, although people don’t always write all the letters in their name in a signature as it morphs over time.
