Ron - This is from the LA Times:

Obama was born in Honolulu. When he was 2, his father, Barack Obama Sr., a Kenyan, and his Kansas-born mother, Ann Dunham, separated and later divorced. Dunham later married Lolo Soetoro, who was a Muslim. In 1967, the family moved to Jakarta, where Obama lived from ages 6 to 10. People there knew him as Barry Soetoro.
