Notwithstanding the purported allegation under oath in the divorce papers, I have never believed they were married in Hawaii. Until proven wrong, I am going to speculate that they were married in Kenya.
But, like the birth, the negative allegation that there is no report of a marriage in Hawaii would only stand up until someone finds a Vital Statistics report or other news local vitals report.
I personally don’t believe they were born in HI either. But, just ‘if’ they were born in HI, Stanley Ann would either have had to use a fake ID or have had the written permission of both of her parents to get married.
