Kay, I am sorry but I know nothing of Mary Elizabeth Scott or anything about the Yarborough family. Edwin Scott did not name any of his family in his book (which disappointed me a great deal). He only referred to them as "my father (whom I happened to know was named William), my mother (Roxanna Anderson Scott), my brothers and my sister. I have heard that many of the Scotts moved to the Mississippi territory in the early 1800's, but Edwin's family stayed in South Carolina. If I happen to run across any information on the above, I will email you. Blanche
