There's unknowable material real facts that nobody will ever know though. I read into one a few years ago when I was trying to find when the last American slave died. The problem is they were considered property so no documentation or birth records were produced. The lack of record keeping made this an impossible question. The last documented one was in the 1930s but the last civil war veteran died in the 1950s, surely there was some baby of the 1860s that was born into the system that probably survived until at least the Montgomery bus boycott or Brown v. Board. But this is something I discovered is a factual statement that's impossible to verify and will never be resolved.
