You said — “Or maybe her family just wanted it out there that Ann had actually married Barack I and that Barack II was not illegitimate.”
So, you’re saying that she just went over to Kenya for “show” and didn’t get married? Is that it? I don’t know.
But, I do know that the grandmother of Obama says that she was there when he was born in Kenya...
I don’t know whether or when Ann went to Kenya.
My comment was as to the birth announcement and why it might have been published.
There’s always a chance it was published to make Ann’s situation socially correct-—she was 18 after all. She may actually have been married and married at the time baby Barack was born, but it probably wasn’t a conventional situation with a big wedding, showers, and so on. Maybe her family simply wanted to announce that Ann wasn’t a floozy teen, but a married woman who had legitimate child. Just in case the neighbors were wondering.
