The doctor (begins with an “A” - I left the name out because I can’t remember how to spell it) was actually traveling around Africa with a vaccination program he headed. He was one of the doctors in attendance at the birth. The name also has an apostrophe in it, IIRC. A thread here dug into his whereabouts versus his name being on the Smith BC and the conclusion was - nothing ruled it out. I think the proximity of the doctor and Obama Sr. was later in life, not at the time of the birth of BO. Or maybe it was prior to...darn brain can’t remember which :-).
IIRC they lived near each other in the ‘70s. At some point the doctor (canNOT remember his name, first began with “J” I think, last name was an African name strange to me) waw murdered.
