If this is the same man that I have in my tree, I have it spelled Fretwell Goulsby Hensley born about 1831. Son of John Hensley and Mary Smith. He married Edicy McCallister, d/o Richard McCallister and Sarah Nicholas. This spelling may be wrong as well, but I have seen that spelling before with another person. I haven't researched the Hensley family, but he just happened along while researching the McCallisters. May be an altogether different fellow, but quite a coincidence to have the same unusual name.
