Well, I have found a wealth of information from an unlikely source;
The FBI. My daughter's paternal grandfather was what the FBI call a negro agitator under the title of Racial Matters, Well thanks to them I have collected every addres he resided the day of his seperation,family members names and address, a small portion of information was blacked out, but this file will be declassified every few years. I am certain the FBI kept a few files on many Black Americans

Peace and Blessings
