Monaghan, Grandfather of Buck

This is one of Faulkner's characters who are defined by absence and indeterminacy. When the aviator Monaghan explains his "Shanty Irish" origins, he gives a memorable description of his father, but he cannot trace his ancestry before that: other than saying his father came "out of a peat bog," which suggests the Irish peasantry, Monaghan claims, "I don’t know what my grandfather was. I don’t know if I had one. My father don’t remember one. Likely it could have been one of several" (415).
