The question remains, why would Madelyn Payne Dunham misspell her own christian name and the name of the Street?
The first two signatures on the Hawaii 'document' appear to be written by the same hand.
I do not see this as a 'birth certificate' but as an application. From which a certification of live birth was FILED.
NOT ACCEPTED.
If the application is genuine, we must ask how was it obtained? And who filled in the form? I very much doubt that Madelyn had anything to do with it. Who might it have been that didn't know how to spell Madelyn...nor the the name of the street? A foreigner to Hawaii?
No that is the form. The way it is usually done is that the mother or someone else, supplies the information, it's typed up at the hospital on this form, which is then signed by the appropriate people in the appropriate places. For a birth not in a hospital, in 1961, it might have been filled in by hand, and their would likely not be a "local registrar" signature, (block 21), which is usually a hospital official. The "witness" could be a relative or friend of the parent(s), rather than a doctor or midwife.
