From New York Times article:
"When President Obama lands in Yangon on Monday, he will be the first sitting American president to visit the country now known as Myanmar. But he will not be the first Obama to visit.
The president’s Kenyan grandfather, Hussein Onyango Obama, spent part of World War II in what was then called Burma as a cook for a British Army captain. Although details are sometimes debated, the elder Mr. Obama’s Asian experience proved formative just as his grandson’s time growing up in Indonesia did decades later."
"Either way, Burma was a place of awakening for Mr. Obama’s grandfather, a place where larger possibilities first presented themselves. But whatever ambitions he began to harbor then, he could hardly have imagined that seven decades later, his grandson would return to Burma aboard a blue-and-white 747 known as Air Force One."
