I am descended from Thomas Briight who was in Washington Co. or Sullivan Co.VA in 1783 when his daughter Susan was born. Land records also show a James Bright, either a son or brother I surmise. Susan married Jacob Maggard, son of Henry, and early Sullivan Co. land records only show Thomas and James Bright and Henry Maggrd. ABright and CampbellMining Co.appears later.
Jacob and Susan Bright Maggard's daughter Elizabeth Ann marrried John Johnson in Randolph Co.MO. His mother was Elizabeth Campbell born Botetourt Co.VA, daughter of Thomas Campbell and Jerusha Titus.
It is my belief, based on all my family lines, that this Thomas was descended from Franccis Bright of early MD, and I suspect that he was the Thomas Bright who owned land in Rich Valley of SW VA before moving into area around Bristol VA/TN.
