Sam, I don't remember passing along one of our missing Williams. He was a son of Benjamin Blackburn and Rachel Mathes-grandson of Archibald and ggrandson of Benjamin and Mary of E. TN. The Challacombe book lists William "left home and never heard of". I don't have a birth date but believe it was probably between 1815 and 1825. Siblings of Wm.: 1.John Blackburn "moved to Missouri" no further info. 2. Elizabeth Blackburn "moved to Missouri" no further info. 3.Ebenezer Blackburn "moved to GA and died shortly" 4.William 5..Archibald Blackburn, "died at home" 6.Louisa m Mr. Gillespie of Blount co. TN 7.Isabella "married Dr. Gillespie, son of Louisa's husband." 8. Lucinda "married a Mr. Taylor of blount Co. 9. Nancy m Dr. M.F. Gerald, M.D. 10. Amanda m Campbell Teahorn and moved to California. If our speculations are correct about Doug's Cass County William being a son of Archibald Blackburn , then these would be his nieces and nephews . Good hunting Miriam B.
