I don't remember the book that this tax district map was published in, but it's on p. 134 of the Caswell County 1784 Tax List compiled by Henry Kendall. You can draw the map yourself:
Divide a rectangle into 8 equal sections, 4 sections on the top row and 4 sections on the bottom. The top row sections, from left to right, are: Caswell, Richmond, St. Lawrence, and Nash. The bottom row sections, from left to right, are: St. David's, Gloucester, St. Luke's, and St. James. These were the districts of Caswell County from 1777 to 1792. Person County was formed in 1792 from the eastern half of Caswell County, and included districts St. Lawrence, St. Luke's, Nash, and St. James. The other four districts formed Caswell County. Caswell Court House name was changed to Leasburg in 1788. It is in the lower right corner of Richmond District. Hope this helps.
