How do they know this was Obama?
Gee, I dunno, how many kids named "Barry Soetoro", claiming to have been born in Honolulu, Hawaii, on August 4, 1961, could there have been in the nation of Indonesia, in the late 1960's?
I'm guessing just one.
[Or maybe you were being sarcastic?]
duh i dunno......
To answer your question:

Israella Darmawan is every inch a teacher, from her shiny cap of black hair to her sensible shoes. In an office at the Fransiskus Assisi School, she shows me an old register with an entry for Barry Soetoro, as Barack Obama was know then. Bu Is taught Obama in the first grade. She admits she doesn’t remember all her students well, but Barry ... well, he stood out.
His stepfather is listed on the form as well. AFAIK, the stepfather didn't have another son named "Barry". It would be rather odd for an Indonesian.
That is the name on his real birth certificate
