Click on "Traughber" and then on "William Traughber (c1740? - c1826)"That will take you to a short paper on this man's family.William C. Traughber was one of his sons.
As you will see in that paper, there are references to all the records I found in Logan County as well as an excerpt from an old letter written by William C. Traughber's nephew regarding the family.
William C. Traughber had eleven children, who are briefly described.James S. Traughber was, I presume, the same person buried in the Traughber-Cook cemetery, which would make him the youngest of the children. He can be tied to William C. Traughber by several deeds in which he bought his sibling's interests in his father's estate.
