She was 16 years old when Barack Sr married her. There is insistence it was a "tribal marriage" and he was free to marry again. She gave birth to Auma in 1960. I believe Auma is in the USA. Her husband was well on his way to the United States before his daughter Auma was born. He was married (it is believed) to Stanley Ann Dunham in 1961.
Stanley Ann later divorced him and he then married Ruth Baker of New York in 1965. Besides two sons with Ruth, he "went to" Kezia yet again. Abo was born in 1968 and Bernard born 1970 to Kezia.
Some family members dispute the parentage of these last two males. You will probably know most of this, but I just thought I would rattle away on the subject of Kezia.
I also should have noted that prior to his leaving for the USA in 1959, Kezia already had a son by Barack Obama Sr. His name was Malik.
Sounds like Obama Senior shoulda been gelded early.
