Sure, it could have happened, but the evidence suggests it did not. If Stanley Anne was sent to live with her Aunt Blaine, why is it she was living openly and alone with her biracial child in Seattle a month or so after the birth?
Sorry, but the facts just don’t fit your scenario.
Perhaps because she wanted to attend the University of Washington, which is LOCATED in Seattle???
If she wasn't ashamed to live alone with a biracial child in Seattle, why would she be embarassed to give bith in Seattle or Hawaii? What's the point of flying from Hawaii to Blaine to give birth, only to then move to Seattle 6 weeks later?
