Acknowledged paternity and/or the birth is registered there. Much has been made about leaving the 9 space blank. Is it possible another clerk, many years later when presented the Kenyan BC simply filled in information from it? AfriKan was the term used in Kenya for a person of one of the native tribes and SR would have qualified for that.....FRmail coming your way.
That would be 1971 if so. Obama Senior had a reason to be in Hawaii in 1971 to assist in some manner with the 'transfer' of his namesake son. After reviewing Indonesian laws his official paternal status would have allowed for the termination of Obama II's Indonesian citizenship and eliminated all citizenship issues with that country for the young Obama.
And if Obama senior was used a conduit to legally and cleanly transfer Obama II out of Indonesia that would have establish or re-established Kenyan citizenship.
The records all had to be touched and possible updated in 1971. Thus this may be a wormhole of records period.
