Just an FYI, the Roanoke library on Jefferson street will look up any obit for you if you have at least a month and year. They do this service free and by email if that helps you any. Have you checked Patrick county for any burial and cemetery records on your William? Sometimes the main or county library of Patrick county will have cemetery books they can look him up in . Maybe they can find him for you, his burial anyway..good luck to you if you decide to look into this.!!!
