In 1961 no passport was needed to come from Vancouver to Seattle.
The rules for flying in on airlines were different from crossing the border by automobile.
HM, I’b beginning to think that the Vancouver connection may be the key. The missionary in Kenya who had connections in Vancouver is just too coincidental. Wish someone would go to Vancouver and search for any existing homes for pregnant girls in 61. Also dig for records for some kind of “footprint” SA might have left there.
I take that back, it was a birth cert and drivers license that was the requirement. I was thinking of what another person said about flying from Kenya.
