You sould look on this website www.wvculture.org they are listed under the name Shepperd death date of 4-8-1941 for Willis & Howard's death date was 4-7-1941. They died from a dynamite explosion. I can look up the microflim of the newspaper for a couple dollars plus postage if want me to get you the copies. You can print death cert. copies from the above website. The Mingo County Gen. Soc. was glad to help.
