Will Varner - "the justice of the peace and the chief officer of the [Frenchman's Bend] district" to whom Bookwright surrenders himself (90) - is a minor character in "Tomorrow" but a major character the larger Yoknapatawpha saga, appearing in eight other texts.
The "road to Memphis" on which Buck Thorpe is caught driving a small herd of stolen cattle (90) is probably the same road on which, about fifteen years earlier, Isham Quick and the Thorpe brothers ride to the Fentrys' farm, and also on which, two or three years later, Gavin and Chick drive from Pruitts' farm to Frenchman's Bend.
The road on which in Sanctuary Popeye drives Temple Drake to Memphis after raping her and killing Tommy at the Old Frenchman place doesn't go through Jefferson. It is possibly the road on which Faulkner locates "Suratt's" on his 1936 map of Yoknapatawpha, though as drawn that road wouldn't take Popeye all the way out of Yoknapatawpha.
