When describing the people who gather to stare at Joanna's murdered body and her burning house, the narrator of Light in August refers, briefly but very specifically, to three categories of people who are not just from the county or the "immediate neighborhood" or from town (287): one of these categories consists of "southerners who had lived for a while in the north" who, like "the poor whites" and "the casual Yankees," identify the crime as the work of "Negro" and actually "hope" that Joanna had been "ravished" as well as murdered (288).
During his fifteen years on the road, Joe has sex with many prostitutes. In what the narrative calls "the (comparatively speaking) south," whenever he doesn't have money to pay them, he tells them afterward that he is "a negro" - a kind of race card that apparently puts the transaction so far outside the bounds that all Joe risks by asserting it is a cursing from "the woman and the matron of the house" (224).
This boy is born in Joe Christmas' cabin on Joanna Burden's property on the same day that Christmas is lynched in Jefferson in Light in August. When Hightower asks his name, Lena says "I aint named him yet" (410). Joe's grandmother, who is there at his birth, calls him "Joey," confusing him with the child who was born to her daughter Milly, whom she has not seen since he was a baby over thirty-six years ago (397). Lena's baby's father has abandoned him, but at the end of the novel Lena is taking him with her as she resumes her travels.
When he returns to the Burden place after Lena's baby is born in Light in August, Hightower has a brief vision of the antebellum plantation that it once was, and in particular of "the rich fecund black life of the quarters," the "fecund [enslaved] women" and their "prolific naked children" (407).
In his hunt for Joe Christmas across the Yoknapatawpha countryside in Light in August Sheriff Kennedy is joined by a large posse. There are "thirty or forty" white men waiting for the bloodhounds who arrive on the train the day after Joanna's body is discovered (296), and the narrative suggests this same group remains on the trail through the following week.
In Light in August, this is 'the white minister in Santa Fe" - in other words, he's a Protestant from the U.S. rather than a Catholic priest from Mexico - whom Nathaniel Burden hears about. Nathaniel and Juana hope he will marry them, but as they arrive in Santa Fe they see "the dust of the stage" that was carrying him away (247). The fact that he had been there inspires them to live in Santa Fe "a couple more years," hoping he will return (247). He never does.
According to the story Joanna tells about her family in Light in August, when her father married his first wife, Juana, this saloon keeper lent some mosquito netting to Nathaniel's sisters to use for making a wedding veil.
The people of Doane's Mill in Light in August only there temporarily. A few of them, including Lucas Burch, are "young bachelors" (6), but there are also "perhaps five families" living there and working "in the mill or for it" when Lena comes to live with McKinley and his family (4). One of these people is the "foreman" who serves as Lucas Burch's pretext for abandoning Lena Grove in Doane's Mill; another may be this foreman's "cousin," or he may be a figment of Burch's imagination (19).
Hightower's wife in Light in August is the only child of "one of the ministers, the teachers" in the seminary he attends (479), but this icon represents the imaginary "family" that Hightower invents to explain his wife's periodical absences in Memphis. He tells the congregation she has gone to visit them "downstate somewhere" (63).
While spending time with Bobbie in Light in August, Joe sometimes meets "another woman or two" who, like Bobbie, work for Max and Mame as both waitresses and prostitutes. The narrative says they are "sometimes from the town," but are "usually strangers who would come in from Memphis and stay a week or a month" (199).
