Any pictures of the father?
Arabs of Africa have very negroid features though their noses are often thinner and curved.
I do not have the funds to do a good job of investigation and research on all the question marks on two or three continents.
I’m astonished nobody else, even some investigative journalist, has not bothered to get funded by his journal or paper and spend two or three months at least following up on this.
Needs lots of money and a slush fund to loosen lips and delve into government records in Kenya and elsewhere in Africa, Hawaii, parts of the USA and also needs good French language skills as African countries often use that language and cross checking could run into that obstacle.
I speak French and some other languages but don’t have a penny to spare on a short term project nor can afford to lose current income through extended absence that would mean the income source would have evaporated when I return.
Otherwise I’d nail the truth on all this.
