Im sort of in the position to do just that, but i thought breh was talking about 'mists of ados history' type shyt, not stuff where you can go interview primary sources.
I know dead languages, but none appropriate to the task. I was literally trained as a(n ancient!) historian, yet i too hit a block with my enslaved ancestors last time i worked on it.
I've thought about doing shyt like visiting relatives, known and unknown and asking to see stuff like journals, memoirs, photos, relics and asking them about their life stories, cultural practices etc.
could always start with your own family. I remember my family traced our lineage, they sat us down and had us watch a video on it too. Gotta see where that is.
Could always research the Atlantic World Historiography too, talks about how all the coasts touching the Atlantic were/are their own nuance.
I know in Charleston theres a certain type of screw developed in Africa that was found in some forts or Architecture.
I got a couple of journals and books in other languages that talks about "Blacks" being over here first. A lot of sifting through the mists of this history is just keeping your eye open and getting lucky.
Heard a white dude on Destiny's stream even admit the consensus in some academic circles is that Black people did sail over here but couldnt come back due to the Atlantic currents
Theres a lot of places to start
