Several Obama-friendly biographers went to HI in the course of their researches. None of them could find a trace of SAD in HI for the bulk of her pregnancy. [The only indication that she may have been in HI for even the first couple of mos of pregnancy is a notation in a record book. It purports to show the date at which her secretive marriage to O Sr. took place.]
David Maraniss is the bbiographer who established positively that SAD and the baby at no time resided at the address listed in both the birth announcements and forged LFBC. The results of his research have never been challenged.
This was over fifty years ago and I doubt they were putting ads in papers or commercials on radio and tv announcing her pregnancy. They kept quiet to avoid embarrassing Davis’s wife and to eventually find a suitable stand-in. The stand-in was the Kenyan.
I don’t know why you think that address is important. It”s not.
