I have Obama’s first visit to Africa in 1985. Some reports have the visit as late as 1987.
It was Kezia, Obama Sr.’s first wife, who said, “The first time I met Barack Jr. was when he came to Kenya in 1985. He was so much like his father, his looks, his voice, everything. It was like seeing my husband all over again.”
There are other reports that place the time frame, “...four years after his father’s death.”
maybe he married the father’s widow? That does happen in middle eastern cultures.
