On the 1910 and 1920 Census he was King W. Wilson. Does anyone know if King was used as a given name or just a nickname. Maybe this is why we can not find King H. Newby we don't know his real given name.
Another interesting thing is the 1900 Census for the Wilson family at Family Search.com shows Lettie Wilson with her husband's name as James C.Wilson. The writing isn't very clear and if you didn't know his name was Samuel W. Wilson you could think it said James C. but this is just a reminder that the names on the index are not always correct so just keep looking. I'm not saying anything bad about the wonderful people putting the index together.
