The Canada angle really has me wondering. You are so right about travel in the early 60’s. I don’t know, as weird as they were, we have to think about what life was like in the 60’s, not now. I have a hard time believing that the Dunham’s would be fine with their 18 yr. old daughter leaving to Washington with a newborn alone to start school.
It makes sense that the baby was born in the Seattle area, possibly British Columbia, after the parents sent Ann to a maternity home there months earlier, before she started “showing.” Explains why she was there with the baby in August and why she enrolled in U of W there that fall. The geography fits.
The birth could have been registered in Hawaii, either then or later when 0 was adopted by Soetoro.
It would also explain why no one can find evidence of a Hawaiian marriage and why there have been no eye witness accounts of a pregnant Ann in Hawaii.
It fits, but who knows?
Are there any Seattle/Vancouver area FReepers willing to do some digging in vital records?
