No, I don’t. My mother might. I have something similar to the COLB.
That said, you are talking about a completely different issue. The claim here is that any doctor should remember every baby they ever delivered, and that is absurd.
That is not the claim. The claim is that they would remember delievering a black baby from a white mother. In 1961, when such things were much rarer than today, even in Hawaii. Add an exotic name like "Barack Hussein Obama" and ones memory would surely be stimulated by hearing that name again, from a sort of Black guy who is running and/or just been elected President.
You also have to remember that in those days there were more GPs than OB-GYN types delivering babies. His mother would have seen the doctor at least a few times, or at least once, before the birth, and then again after the birth, and that for an OB-GYN. IF a GP, then the doctor likely would have seen the child at least a few times. Stanley Ann would not have gone to some "free clinic" or even the public charity hospital, given her mother's position. ...if they lived in Hawaii for those first few years. The doctor who delivered me, and my 6 year younger brother, also did my pre-college physical and I think my brother's as well (my brother is only 5 years older than BHO). I think that was the last time I saw him. Dr. Place was his name.
