Looking for George Wiley Woodard of Lincoln County Tenn

My g-g-grandfather, George Wiley Woodard is listed as born in Lincoln County in 1843.
There are civil war records when he was 17. He married in 1864 to the sister of a friend he met in the war - Louisa Bunn.

I know he stayed in Lincoln County because both Thomas Wiley (1868) and George Henry (1892) were born there.

I have been unable to find the death records for either George Wiley or Louisa. Can someone help?
