John, here is a quote from "The Settlement of the Appalachian Frontier" by Danny Dixon (online): "HUMPHREY DICKENSON - Humphrey Dickenson was a brother of Henry Dickenson. He settled in Castlewood in 1769 on the north side of the Clinch River where he built a two story log house later lived in by his brother Henry. This house owned by Mr. Don Gray stood until recently. Humphrey was killed by Indians on a rock in Clinch River in 1778."
I last saw Don Gray in 1995 at a high school reunion.His wife was one of my teachers.He may have a photo of the log house, and if still living, and in Castlewood, a letter to zip 24224 would probably reach him.I know that the property is now owned by someone else, and the cemetery on the property contains the graves of the son Henry and all four of his wives.I think I have a photo of this Henry's stone and that of his last wife, who happens to be my gggrandmother in a previous marriage.My guess is that Henry the Clerk would also be buried there, but there is no marker indicating such.
