The birth of illegitimate chldren was never announced in 1961
No, but is the scanned copy the one in question? Because that says Mr and Mrs. They were married before he was born, correct?
Yea, well that address is not exactly low rent student housing either. Seems a bit rich even for the grandparents, but it could be their address.
Something to check the old Hawaiian telephone books for.
Of course it's entirely possible that he was born in some hospital in Hawaii, Stanley (his mother) gave her parents address and "Mr. and Mrs. Barrack Hussein Obama as the parents name. Or just didn't bother to to mention that she was not married to BHO. The "fake" CLB did show BHO as the father, and gave Stanley's maiden name.
It's also possible the birth certificate, was filed late, after his mother returned with him to Hawaii from somewhere outside the US. (But I doubt it). The Vital records list would still show him as being born on whatever day the birth certificate shows. But unless the date was reported fradulently, it doesn't leave much time for messing around with filings and such. The date is the 4th, and the list was given to the paper, by Vital Records, in time to be printed on the 10th.
