Might be quite intriguing.
The records nurse might well have not been in any position to do the sort of filtering later analysts (Census, HHS, etc.) might do when presented with such materials, so she just wrote down what the correspondents said.
That material would then be reflected in a current document drawing down on the original source materials.
Maybe the babydaddy was present. Maybe he was there and said he was "African" - he might even have been a follower of Ghana's first President, Kwame Nakruma, and he was insistent that Africa (subsaharan BTW) needed to be organized as a United States of Africa for the benefit of the African race.
Yup, I've read all ol'Kwame's stuff and recall a fair amount of it. He was quite popular in the early '60s among African intellectuals ~ all 10 of them ~ (and I knew 4 of 'em - Good lord were those folks in trouble).
I doubt any records nurse would get away with arguing with the elder Barack Obama.
I think it's interesting that modern technology is giving us access to exactly what people said "way back when" before there were any federal impositions on the parlance of ordinary people about what "race" might mean.
BTW, in UK "race" means "ethnicity", and among dog breeders "race" means "descent" ~ not that any of that is relevant, but Hawaii was a UK property before it belonged to the USA.
A few years back I sent for a certified copy of my BC in order to draw social security. I pulled it back out the other day to take a good look at it. It has the same green basket weave paper as Baracks, but the ORIGINAL information was put on what looked like a ledger stock. This was then laid in a copy machine (as near as I can tell) and was then copied onto that green basquet weave paper. I know it was the orginal because it was all filled out in my mothers hand writing. All except my name which was later typed in. I was born at home and evidently they weren't sure what to name me at the time she filled it out. It has all kinds of information on it. What was their occupation was, how many births she had, how many still living, what kind of medicine was put in my eyes by the doctor, and what color was I? That box was maked with a W in my mothers writing. Then it had the embossed state seal, with a signature and the date this certified copy was done.
