Very likely a freedman also. Check the dates. Born well before the American Civil started. Died well after it. Given where we are, I expect he knew the taste of freedom like few of us ever will. Of course, this is total conjecture on my part. There are a thousand other histories he could have lived.
Whatever and whichever it was, I hope he lived it well. He does now rest at the head of the class, so to speak. (He's in the front row.)
