I have emailed a response to this post, but also including here for other researchers who might be interested at a later date:
James Otis Collette was born on 10/13/1901 and died on 11/10/1958 at the age of 57. His parents were Charles Collette and Mollie Vitatoe. He is buried in Oak Grove Cemetary in Rockwood. All of this came from the Booth Funeral Home Book.
The name Collette shows up two ways in Roane County, with and without the last E. They are related somehow, but haven't exactly figured all of them out. I didn't find a Clara Collette in the Booth book though.
The other listings that would be significant for you are:
Probably the mother:
Collette, Mollie; b. 08/22/1880, d. 03/26/1964 at the age of 83. Parents listed as: Joseph Vitatoe and Elizabeth Hayes. Buried in Odd Fellows Cemetary, Rockwood.
Collette, Reba Bernice, b. 07/03/1905 and d. 10/12/1960 at the age of 55. Parents listed as Charles Collett and Molly Vitatoe, buried in Oak Grove.
Collette, Edward, no date born listed, d. 11/15/1972. Parents listed as Charles Collette and Mollie Vitatoe. Buried in Smyrna Cemetary, Rhea County.
Collett, John Andrew, b. 02/02/1931, d. 04/21/1952 at the age of 21. Parents listed as James Otis Collett and Clara Mae Aikens, buried in Oak Grove Cemetary.
1920 Roane County Census:

Mollie, wife, f w 34, cannot read or write, born in Kentucky
Jim, son m w 18, single, can read and write, born in Tennessee

Robert, son m w 9/12, single, born in Tennessee
Vitatoe, Elizabeth, mother-in-law, f w 80, widowed, can read, cannot write, born in Tennessee.
Right now, that is all I have. I believe these are also relatives of ours, but haven't connected them yet. The name Collett and Vitatoe are in our Warner side of the family.
