Burgess, listed in the Cherokee Co., SC Limestone Springs 1910 census next door to his dad Lewis Humphries and Mary A. Humphries.Lewis had about 6 children by Mary A. [?] including Ed H. and his brother James Little Humphries.Lewis later married Mary Hoover and had several children by her, including Aubrey and Hyrtle. Lewis was a son of David Humphries and Artessia Jones (David was a brother to Clayborne, which is mentioned in your book).
