The William Simpson of Chowan County that I have found who died in 1799 named Sarah as his wife in his will. His will was written 24 Sept 1799 and proved in Dec Term of Court 1799, Chowan County. He names a daughter Maryan Skinner. Ha also had sons, Evan (Exum), Robert, William, Demsey, Frederick, and John; also three other daughters Mazy Williamson, Lovey Parrish, and Sarah Simpson. Did the William you mention have a will? Did he orginally come from New Hanover County? Sounds like there must have been two different William Simpsons, one with a will and one without.
