I stand corrected. It has been awhile since I have read the details on Stanley Ann’s life. If she hadn’t returned to Hawaii within a year of his record being filed, that is a hole in the theory.
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.
