As far as African American cemetaries go, I know that there is a very old one out at A&M College containing many graves of slaves. Also there is one located near the corner of Oakwood and Jorden Lane in Huntsville that is still in use today. There was another one, but Huntsville Hospital was built on top of it. I don't know if they ever found were or if the graves were moved to. I do know that they were doing research, but don't know how far they got with it. I'm sure that you could find out allot of information out at A&M. Sorry not much help I know. Dale L. Blackburn Huntsville, Alabama
