Hey Terry,
Below are a couple of links that might interest you. On one it mentions a black CS Marine that served aboard the CSS Alabama. Here they are:

2.http://www.navyandmarine.org/ondeck/1862blackCSN.htm -There is a black CS Marine listed that served aboard the Alabama.

I am curious about any info on the CSS Tennessee that I can find. I have tracked down five of its guns, with pics. The last one I have heard of its whereabouts being in front of the Surflant bldg at the Norfolk Naval Yard or base somewhere up there. But I have seen no proof of this. I wish I could get a pic of it.

I am also trying to find out the whereabouts of the Albermarle's two cannon. I have found one and a pic of it, in front of some building in or around the Norfolk naval base. I have heard the one from the CSS Tennessee that I am searching for is sitting beside it. But again, I have seen no pic and have no proof of this.
Take care,
Dave
