I came across Ken Hammock in Billboard magazine while doing some research on Goldrush Junction in Pigeon Forge.  I didn't know anything about him, but there's a nice write up on him at 
Mellow's Log Cabin blog.
A look on ancestry.com shows a Ken Hammock, age 18 in the 1940 US Census.  His family is living on Dameron Avenue in Knoxville, Knox County, Tennessee.  His father, Otey, was a stationery engineer in a dairy.  His mom, Thenie was not working outside the home.  His older brother, James, was a filler rubber at a furniture manufacturer.
Ten years before, in the 1930 US Census, the family was living at Dameron Avenue as well.  Otey was a laborer at a cotton mill.  Thenia was a laundress.  James, 18 then, was a clerk at a grocery store.
Aside from being a musician, Ken Hammock was also a veteran.  He served in the army during WWII and is 
buried at the Tennessee State Veterans Cemetery in Knoxville.
