Grandfather Compson
His first name is not given in this novel, but he appears in a dozen more Yoknapatawpha fictions (more than any other Compson), and several of them, including the "Appendix" to The Sound and the Fury that Faulkner published in 1946, identify the full name of the paternal grandfather of the Compson children as "Jason Lycurgus Compson." He is the second Compson with that name; there are two more who appear in the novel: his son Mr. Compson, and Mr. and Mrs. Compson's third child, who is Jason IV. The "Appendix" also identifies this Jason as the son of the Quentin who was a Governor of Mississippi before the Civil War. "Grandfather," as Quentin calls him, served in the Confederate army as a General. Quentin associates him with Colonel Sartoris, and idealizes the time in which that older generation lived. In many texts it is clear that he lived long enough for Quentin to know him personally, but that is not obvious in The Sound and the Fury.
