Wellman's great, but not particularly scary. Old Gods of Appalachia has a podcast that's probably a must-listen before running the game.While there are things horror games will have in common, different games/settings will have tonal differences. Alien is different from The Body Snatchers is different from Hellraiser is different from The Stand ...
My inclination based on the name is to suggest you go read you some Manly Wade Wellman.
King and Bradbury have a lot of great rural horror stories as well.
