Presently dealing with where I would/ should look for registries of free colored people for Hamilton County, Ohio 1820-1865. (My concern is that those records were destroyed in one of a couple of fires that affected the Hamilton County Courthouse in the late 1800’s.)
Another issue I have experienced is lack of cooperation (or lack of knowledge) of anyone in the AME church for Ohio or Kentucky (or any other colored/ Black churches) that could assist with church records. Lack of access to church records is extremely difficult, but could help with so much if they would quit throwing stuff away, or denying access to researchers when records still exist.
