Barak Obama, Sr. signed his name without a “c”, so I would think if he supplied the COLB info and named his child after himself, he would have named him “BARAK” like himself.
I saw his name and signature on an African article he wrote.
Therefore, I am inclined to believe he did not provide any of the info for the COLB.
That is certainly possible. The mother might have supplied all the information for the birth certificate.
I can conceive of a hospital clerk asking Ann Dunham: “What is the father’s race?”
And her responding: “Well, he’s from Africa.”
