The answer comes later in the thread, that was about the time of Ann’s divorce. I was asking what happened in that time frame, I just phrased it badly.
Turns out that's the right question to ask. It's been pointed out that the Republic of Kenya came into existence on 12 December 1964. However, it issued this certification on 17 February 1964. Oops.
Meanwhile, Orly Queen of Birfitania is reportedly headed for the UK to check the Kenyan colonial records for Book 44B, page 5733. Lot's of luck with that!
I forecast this one has a short half-life. Not as short as that one with the taunt in the EXIF. But short, nonetheless.
