I am also related to Angus and Dorothy Alexander. I believe his parents were Travis Alexander (b in 1765) and Fanny Denny who come from Wilkes County, NC. I believe Angus also came from Wilkes County. I have actually been trying to locate my ggg grandmother, who was supposedly a daughter of Angus and Dorothy, her name was America. I have not been able to find her on any list yet as their daughter. Have you seen any other people who were listed as living in their house? I will try to find the site that listed the parental information and post it here for you. I believe that some information can be found on the Madison County, KY website.
