Hello:
I also do family research in Sevier County, and a quick perusal of my Internet sources revealed that Benjamin F. Jones, husband of Nancy Samuels Jones, died 1866 in Sevier County. This information came from two different genealogy reports (there were several others, but each gave Benjamin’s marriage date as his date of demise). If you wish the names and e-mail addresses of those two researchers, contact me at horizonstravel@sbcglobal.net. Perhaps they can give you valid sources for that information. I can’t guarantee the e-mail addresses are current.
