Stanley Dunham was a vivid American character. He grew up in El Dorado, Kans., an oil town in the 1920s that declined sharply in the Depression. He was himself abandoned by his own father, and his mother committed suicide. (The 8-year-old Stanley discovered her body.) Like Obama, Dunham was raised by his grandparents. But in spite of—or perhaps because of—their devout Baptist faith, Dunham was something of a rebel and a drifter. He was kicked out of high school for punching the principal, and spent the next three years riding rail cars. He was a charmer and a dreamer who courted his Wichita girlfriend Madelyn (Obama calls her "Toot") even though her parents—Methodists and more middle class—disapproved. The young couple eloped just before Pearl Harbor. Stanley enlisted in the Army while Madelyn worked on a bomber-assembly line. After the war, he found work as a salesman in a furniture store first in El Dorado, then moved from small-town Texas to Seattle, finally settling in Hawaii. Stanley styled himself as a freethinker and apparently raised no objections to his daughter's marriage to Obama, and he cherished his grandson.
Barack Obama's half-brother, also known as Abongo or Roy, was born c. March 1958,  the son of Barack Obama Sr. and his first wife, Kezia.  Malik Obama was born and raised in Nairobi , Kenya.  He earned a degree in accounting from the University of Nairobi .  The half brothers met for the first time in 1985  when Barack flew from Chicago to Washington, ., to visit Malik.  Malik and his half-brother Barack were best men at each other's weddings.  Barack Obama brought his wife Michelle to Kenya three years later, and they met with Malik again while meeting many other relatives for the first time.
