Obama Sr. went home to Kenya to welcome Jomo Kenyatta.
Jomo Kenyatta was being released August 14, 1961, after serving time for his part in the Mau Mau uprising in 1952. Obama Sr. was a big supporter of Kenyatta and would later serve in Kenyattas administration as an economist.
I suspect the Stanley Ann found out about wife #1, Kezia. She doubtless was angry at being married to a bigamist, and after Barry was born the shine was off the marriage. That is why she went to Seattle and the U of W in Sept.61 rather than return to Hawaii. She didnt return to Hawaii until Obama Sr. went on to Harvard.
