Yes, that’s the one I was referring to. It doesn’t ask for a relationship. That section is specifically for children. The passport application is a U.S. application. Soebarkah, Soetoro and Jakarta are the only “Indonesian” words on there, so there’s nothing her that would presume that it’s not part of how the child was identified ... i.e., a name or nickname.
So Obama used his adopted name “son of Soetoro” in Indonesia? I wonder if that is the name on the passport he used no one is allowed to see.
