He's made his spreadsheet available to others. I grabbed it and extracted the games that Knoxville / Tennessee was involved with. I'll look at the first two known no hitters.
On August 22, 1912, Finis Wilson threw one against the Johnson City Soldiers. This was Fin's second season playing for the Knoxville Reds of the young Appalachian League.

The article in the New Orleans Item has the game scores reversed but does share that Fin Wilson pitched both ends of that double header.

The shortstop Morley was Bill Morley. The 1913 season he played two games for the Washington Senators of the American League.
It was almost a full ten years before another no hitter was tossed by Knoxville. By this time the team had changed its name from the Reds to the Pioneers.
According to McGill's spreadsheet the second no hitter was tossed by "Red" Stoner on July 7, 1923 against the Kingsport Indians. McGill's spreadsheet has the score listed as ?-0.
The SABR Minor League Committee newsletter for the Spring of 2007 was seeking the info.

Not much is known about Mr. Stoner, except that he went 17-6 for the Pioneers that season.
And that he was sold to the New York Giants in August.

Apparently the big baseball news coming out of Knoxville at the time of Stoner's no hitter was that Frank Kane was released from the team.
