Tubbs, the jailor, tells Nancy that he has "found that preacher" she requested (221). He never appears in the text, but it's safe to assume that he will be with her when she is executed - after sundown on the day the novel ends.
Nancy tells Temple and Gavin that "any of them" might have been the father of the child she lost (219). "Them" refers to the various men she has had sex with, as both a woman and a prostitute.
All we know about "the man who kicked" Nancy and caused her miscarriage is that he might have been the unborn child's father (219). Because the assault happened at "a picnic or dance or frolic or fight" and Nancy would not have been allowed to attend a gathering of whites, we are assuming this man is black (219).
Jailor Tubbs refers to the man whose job it is to arrest "drunks and gamblers" only as "the Marshal" (209). In Faulkner's Yoknapatawpha fictions the "marshal" is a peace officer whose jurisdiction is the town of Jefferson.
