So, will daddy be Davis, Malcolm, or Ayers?
It might not matter. The husband of a married woman is legally presumed to be the father of her child. Generally that's true even if the BC names someone elee.
Unless the divorce papers are fake, or fraudulent, then SAD was married to BHO Sr when Junior was born.
One, somewhat "out there" theory says none of the above, but rather "Grandpa" Dunham, with some dark hued bar girl as the mother.
The person married to the mother is presumed to be the father & recognized by law as such. So, the marriage, the name on the birth certificate (all the bc’s show the same father) ane the divorce. All make BHO Sr his birth father. So, born in Kenya or Hawaii, bho is a dual citizen, ineligibile to be POTUS.
