There is a Thomas Hissom (also spelled Hysham)buried in Tyler County WV. He was a known revolutionary war soldier. Additionally, there are numerous Hissoms in Ohio WV (Monroe county Oh Tyler County WV). SPellings include Hisam, Hissem, Hissom, Hissam. My mother is a Hissom, her family coming to WV from Monroe County Oh. I was always told it was an Irish name.
