There was no obituary in "Crossing the Dark River", deaths of Henderson Co. area residents, for Clifford L. Duke. The death certificate of Clifford L. Duke should tell you the cause of death. It might be available at Tennessee State Library and Archives in Nashville. Visit below for information on TN death certificates. http://www.state.tn.us/sos/statelib/pubsvs/vital3.htm Funeral records might be available. Call or write: Pafford Funeral Home, 71 Monroe Ave, Lexington, Tennessee 38351 Phone: (731) 968-2544 or Reed's Chapel , 302 W Church St, Lexington, Tennessee 38351 Phone: (731) 968-3643 Sometimes The Jackson Sun newspaper in Jackson, Madison Co. TN, published deaths of people who died in Henderson Co. TN. Contact Tennessee Room at Jackson/Madison Co. TN Library and ask volunteer for lookup, providing date of death. Email: tnroom@aeneas.net Perhaps there was an article about his accident in "The Lexington Progress" newspaper, Lexington, TN. Order microfilm of year of newspaper for time of his death and search. Microfilms can be ordered from any local Mormon Family History Library and you might be able to get the microfilm ordered through your local library from Tennessee State Library, if you can't visit in person. For information on how to order from Tennessee State Library go to http://www.state.tn.us/sos/statelib/pubsvs/bymail.htm By the way, there used to be a website for Pafford Funeral Home, but I didn't find one when I used an online search engine and I thought there was an email link on their website. You might try Internet search using your choice of a search engine. Good Luck.
