Don’t let it bother you, no one can be sure WHEN she actually showed up in Hawaii, but the first photographs that appear showing SAD with zero are from when he’s about two years of age, so 1963 would fit.
Doesn’t prove she was his mother.
There are really a LOT of details to try to keep straight with this topic. I find myself constantly forgetting this or that aspect of something I once new about the subject.
I used to exchange messages with a guy who was convinced that Madelyn was his mother, and Frank Davis was his father.
I can see the Frank Davis argument, but Madelyn as the mother? I can't see it. His evidence was a Poem Frank Davis wrote.
Hopefully the full story will come out one day, and hopefully we will all live long enough to hear it. :)
