I am a member of a genealogy society in the community and state where my ancestor's lived. I joined the society and when I need something, because I am a member, they find it and email or snail mail it to me. Since I can't travel to the area, this is a fantastic help.
As of 2007 there is a black genealogy society out of Nashville. I don't know if the officer's are still in place but I'm sure they can pass on your request...

I must also remind everyone, regardless if the societies are run by black or white members, what we are all interested in is information. Membership is only as strong as the members. If there is no local then, join that particular state society for 1 year.
