Except there would have been a problem if Grandma Toot had filed a birth certificate saying “born in Hawaii” and had listed it as a home birth at the Dunhams’ address.
The problem is that there was another family living in that house with the Dunhams. The daughter in that family has already said she doesn’t remember any baby there.
If they were relying on such a birth certificate, the story of where he was born would fall apart as soon as any reporter or investigator talked to that other family.
That would give a motive for forging the birth certificate to show it as a hospital where lots of babies were being born, it wouldn’t matter if no one remembered him and privacy laws would protect the records from prying eyes.
But my point is there would have been no need for the forgers to forge in the name of the putative mother. It would have already been on a document. It was forged in recently, that’s been proven.
