Hussein doesn't really look like Frank Marshall Davis' son, but he looks a lot like his daughter. Lynn Davis was 12yo in 1961, the right age to travel to Indonesia as a gift for Pak Subuh, and to get pregnant by him. Nobody has any idea where this girl was and it is entirely possible that she DID go to Kenya and give birth to him there.
In fact, the area where Barack Obama Sr. lived is near Lake Victoria, the source of the Nile. Could be that Lynn gave birth to Obama near the lake, put him in a basket of rushes and let him float into the beginning of the Nile, where Stanley Ann collected him a little ways downstream.
In any case Hussein does resemble both Pak Subuh and Lynn Davis.
