I flew Toronto-London and back in 1961. A 12 hour job. One look at a map of the world does indicate an incredible distance between Hawaii and Kenya. Three times at least more than I travelled. Stanley Ann Dunham, for all her free thinking was in a vulnerable position. Her man was no support.
That said, I would think Vancouver, Canada a possibility. If not, the actual wishes of the Framers of the Constitution, which probably demanded two American citizens of a child natural born. This on elegibility.
Therein lies the trap IMO. The assumption that a birth record of dubious Kenyan origin must somehow automatically suggest that Stanley Ann gave birth in that country...leading to research into airline schedules...when all that may be indicated is a document was produced for a purpose, probably in 1964.
What purpose? To obtain custody. Divorce was applied for in January 1964. The ‘kenyan bc’ is dated 17th February 1964.
The connection between ‘The Articled Law Clerks Society of Victoria’ - E F Lavender - Melbourne University Law Review and Harvard Law Review...
What might that suggest to you?
