Yes, I have! I have him listed in my book. I found where he and Quantrill raided Midway in Woodford County Feb. 2, 1865. "Sue Mundy" was a fictional character created by George Prentice, editor of the Louisville Journal. Clarke became the proverbial scapegoat.
My sources claim he was captured in a barn near Webster, Breckinridge County, Kentucky, on March 12, 1865. Clarke was not allowed a defense. He was hung, and actually strangled to death, because drop wasn't the three foot drop allowed.
