Who filled it out?
If Stanley Ann did maybe she put African.
If a doctor did maybe he put African since BHO Sr. was an African and not a native.
Shouldn’t be too hard to find up whether other Black parents in Hawaii were listed as Negro or something else.
In all probability, neither Stanley Ann nor the doctor would do anything but sign the purported BC. The task of filling in the other info would fall to a hospital employee who did it routinely. Only certain designations of "race" would be deemed acceptable to the state bureaucrats - that hospital employee would be aware of them - and "African" would not be among them.
