Meet Obama's aunt, Zeituni Onyango.

From timesonline.co.uk.

"Barack Obama has lived one version of the American Dream that has taken him to the steps of the White House. But a few miles from where the Democratic presidential candidate studied at Harvard, his Kenyan aunt and uncle, immigrants living in modest circumstances in Boston, have a contrasting American story."
Zeituni Onyango, the aunt so affectionately described in Mr Obama’s best-selling memoir Dreams from My Father, lives in a disabled-access flat on a rundown public housing estate in South Boston."
"Speaking outside her home in Flaherty Way, South Boston, on Tuesday, Ms Onyango, 56, confirmed she was the “Auntie Zeituni” in Mr Obama’s memoir. She declined to answer most other questions about her relationship with the presidential contender until after the November 4 election. “I can’t talk about it, I just pray for him, that’s all,” she said, adding: “'After the 4th, I can talk to anyone.'”
"A photograph of Ms Onyango was later shown to George Hussein Onyango, Barack Obama’s half-brother in Nairobi, who confirmed that it was their aunt. George Onyango, 26, the youngest child of Barack Obama Sr, said that he had spent weekends with his Aunt Zeituni when he was growing up, and instantly recognised her."
