My research indicates that Nancy Cavett was a niece of Alexander Cavett, the owner of Cavett Station. Alexander and his entire family were killed by Indians in the 1790s. Cavett Station was located in the western portion of Knox County, Tennessee. You can visit the site, it's located in Mars Hill Cemetery on Broome Road between Kingston Pike and Middlebrook Pike. A marker was placed in the cemetery that depicts the history of what happened.
