Do you have any information about Easter Leeper's parents or birth date?

This following is found in A History of Hickman County, reprint of Spence's 1900 edition, p. 109: "In the upper end of Whitson's Bend, years before the Civil War, Robert Wright built a mill. Nancy, a daughter of Wright, married Major Whitson. Robert Wright was the father of Robert Jr., John, Levin D., and Thomas Wright. The latter was killed in Perry County, near Lobelville, by Dock Leiper, who had married his sister. Leiper claimed to have acted in self-defense. Wright was insane at the time of his death."
