Everything points to it, she's the girl Abercrombie remembers, he calls her Ann, he knew she had a child in Hawaii, that's why he was so convinced he would find a record. He very well could have, but the date of birth and the name of the mother wouldn't match the myth, so he dropped it like the hot potato it would be...
That child keeps popping its head up but it isn't zero, it's the baby Mary baby-sat for Anna Obama in Seattle. It's the child they were considering having adopted. She was the girl whose parents wrote to the INS about (names redacted) wanting to break up the relationship. And it's the child Aunt Zeituni said the kenyan wrote home about, when he told the clan he had a son in Hawaii. He's the little boy on the right of the two little boys image, and that's zero on the left. That dark boy belongs to the kenyan and his wife who moved to the Philippenes - the same dark boy the kenyan and Ruth are shown with in the family group when the dark boy was about four years old in around 1966 when Mark was still a toddler.
