George. W. "Dud" Whitaker was a cousin of Elisha Whitaker b. 1862, d. 1901. Dud also testified at James Mize's trial because he was across the river at Elisha's house when the shooting happened. This chart from my post on Elisha probably explains their relation best:

Fatal Quarrel Over Land.
Somerset, Ky., Aug. 14.--Quarreling over a tract of land, the value of which is but a few dollars, Jesse Morgan, fifty-eight years old, last night shot and i[n]stantly killed Dudley Whitaker, thirty-five, at the former's home, east of the city. Neither man had ever before been in trouble and both were highly esteemed as citizens. A Deputy Sheriff brought Morgan to jail here this morning. The killing is the second to occur in Pulaski county within the week.
