May I propose a possibility for the father of your John Tisdale Draughn? I believe Abial Draughn may qualify. Let me explain.
John Perry (1715-1785) resided in Bertie County from the 1730 to 1760 period adjacent to the family of Walter Draughon. In 1769, John Perry moved from Bertie to a Land Grant he received on Raftin Creek in present-day Sumter County, SC. In 1771, John Perry sold this plantation to the later-famous Thomas Sumter, and moved southeast over the high hills onto what was then-called the South Fork of Black River (still in present-day Sumter County, SC). John Perry owned several parcels of land on this stream, with one parcel located around Green Swamp. This area went from the area of present-day Sumter (the city) southeasterly along the north side of the present-day stream called Pocataligo River. John Perry's plantation was adjacent to the plantation owned by John Tisdel (also spelled Tisdale on some documents).
In 1777 (During the Revolutionary War), John Perry made out his Last Will and Testament, and included "my nephew, Abial Draughn". John Perry, himself, had a son named Abial Perry, so the use of the name Abial is certainly common among these two families. John Perry bequeathed 100 acres to Abial Draughn, adjacent to John Tisdale's plantation. I would think that Abial Draughn probably named a son after his neighbor (perhaps Abial Draughn even married to one of John Tisdale's daughters?). Regardless, another Draughn mentioned in some of the Perry family documentation is the name Hampton Draughn. Hampton Draughn appears to have been of an age to be the son of Abial Draughn, too. If you like, you can e-mail me directly at ZaneDPerry@hotmail.com and I will forward you a copy of a Will of one lady named Nesbit from Sumter County that includes information about Hampton Draughn of that locale. Hampton would certainly seem to be related to your John Tisdale Draughn (if, in fact, he was the son of Abial Draughn.) Please e-mail me directly, as I do not happen onto this Draughn forum often. I can also direct you to a map of 1821 for Sumter County that locates these two plantations.
I should also note that these same Perrys were the world's largest exporters of tobacco from the late 1600s to the mid-1700s. Micajah Perry of London, who is closely linked to this same John Perry family, helped Robert "King" Carter in the 1720s by giving Carter the agency for the Northern Neck in Virginia, which Carter managed from Virginia while Micajah Perry managed the agency from London. I would suspect family ties were long remembered between the Perrys and the Carters, and the Draughns were mentioned in the Perry family Will as "nephew", so obviously these ties were with the Draughns, too.
