It may all be a coincidence, and yes I realize this post is several years following your own. I am african american and my ancestors from Greene County, Eutaw, were also named Harris. I don't know John, but my great grandfather was named Walter. More than likely, he was born around 1875 and died in the early part of the 20th century. He had two sons at least, Homer and Hugo, and a daughter, Anna. Does any of this sound familiar?
