"1906" is the only date I have found in the novel DEVIL MAKE A THIRD. That year appears in a speech given by Alabama Governor Thrasher at the Harrison House Hotel in Aven. I believe the characters of Governor and Mrs. Thrasher are modeled after Alabama Congressman H.D. Clayton, Jr. and his wife.

from page 215 of DEVIL MAKE A THIRD:

"Now," he said, "I want to tell you about these boys and the honor they've done me." He held his head back and looked thoughtfully up at a corner of the room. "Back in 1906, it was. I was campaigning and , as the Senator can tell you, a campaigner is going to drift down to Buck Bannon or get detoured." 

(from the July 23, 1910 DOTHAN EAGLE)
