S. F. Jordan operated a sawmill at Duff, a mile north of Neuville, at least during the years of 1906 and 1907. It may have been the old Garrison & Wragg mill which had been operating a mile to the north in 1904. His equipment included a 9-inch by 12-inch Atlas steam engine, a 10-inch by 12-inch Atlas boiler, lumber buggies, a cutoff saw, a Curtis 30-inch 2-saw edger, and a Curtis swing saw. In 1910, living at residence 200, in Precinct 2, Neuville, the Census lists him as a “sawmiller.”
According to maps at Stephen F. Austin State University's East Texas Research Center, the Shelby community of Duff is located next to the tracks of the Gulf Beaumont & Great Northern (Gulf Colorado & Santa Fe), north of McFarland, south about four miles from Neuville, and one-half mile west of Highway 2140.
