It is positive that the Brits managed East Africa because there were good civil records.
Do you suppose those records (marriage, divorce, and birth) were shipped back at the end of the Brit occupation? I know lawyers in London--investigation would be easier and cheaper there than in Kenya. And further, less subject to interference from Kenya government employees and agents who may well view it as adverse that an effort is under way to disqualify a Kenya native born.
Note that the purported acquisition of the birth records reported in the Wayne Madsen update occurred in Kenya.
I doubt marriage records were created for the Naaaitivezzz anyway.
