“.... it may be when she was 14..... around 1967.” was an estimate on my part.
If it was a couple years earlier, she’s 12, Mark is a few months old, Malik is seven, (not sure if Auma is nine or five, assuming two years at most between her and Malik).
And the huffpost article saying “babysat president’s half brothers and auma” does NOT include the president, otherwise it would have said “babysat president AND his half brothers and Auma”.
So we have half brothers Mark & Malik, and Auma, being babysat by Auntie in 1965 at the earliest, when Auntie was about 12.
About the family pictures of the boys:
Looking at pic that was on Mark’s website, the one with the right hand toddler’s head tilted, and grade school age boys on advance copy cover of Mark’s book,
Toddler on left is same as grade school age boy on left.
Toddler on right has same eyebrow structure as grade school boy.
Grade school age boy on left is younger than the one on the right.
Eyebrow structure of toddler on right and grade school boy on right match the current day Mark.
Therefore the boys in BOTH pictures are Mark and David.
