Charles Neville Buck 
Call of the Cumberlands [EPUB ebook] 

The author was a native of Kentucky and wrote from first-hand experience about the warring ways of rival clans and the fact that progress threatened to bring about an end to their century-old lifestyle. The hero, Samson South, is appealing, and this novel is consistently compelling, whether its setting be the Kentucky backwoods or New York City. (Goodreads)
