The tale of Sherrif Grayson's geneaology is very interesting. He was the grandfather of G.B. Grayson who was the original singer of Omie Wise (you can hear him on the Anthology of American Folk Music). The man credited with introducing the world to the ballad Tom Dooley was Frank Proffit who was a singer and banjo player/maker. He sang it for a collector (maybe one of the Lomaxes?) in the 30's.
