I descend from Andy Hall, Billy's last child by his first wife, Sally Smith. Based on family stories I've heard, Billy Hall's father was a Frazier. A number of years ago, I took a DNA test through Family Tree DNA, (which uses DNA to help with genealogy), and had a very strong match with a Frazier gentleman who lives near Winston Salem. To make a long story short, after years of DNA testing of a number of Halls who descend from Billy and a number of Fraziers, my best guess is that Billy's father was a man named "John Frazier" from Stokes County. Billy's mother was a Hall who, I think, lived around Salisbury, NC. Still trying to identify her. Also looking for male relatives with the surname Hall who descend from Billy who might be interested in taking the DNA genealogy test as well. The need to be direct male descendants, as the chromosome that is tested and compared is only passed from father to son, to son, to son, etc..
