Cap married Nancy Elizabeth Smith (1866-1942) on October 11, 1883 and had the following children: Coleman Anderson Hatfield (1889-1970) who was blind and married Bertha Marie Caldwell (1883-1963) aka Mossie Caldwell; Sheppard "Captain S" Hatfield (1891-?); Levicy Hatfield (1893-?); Pinkie Hatfield (1894-?); Louise "Lou" Hatfield (1896-?); Robert Emmett Hatfield (1897-?); Preston Hatfield (c1899-?); Lionel Weaver "Elbert" Hatfield (1900-?); Georgia "Flossy" Hatfield (c1904-?); and Muriel M. Hatfield (c1907-?).
According to Sam Rogers of the Logan County Historical Society: "The Cap Hatfield Cemetery is contained within the Stuart Glenn property. This six and one-half acres was the home of Joe Glenn, long time local attorney, stepson of Cap Hatfield, and participant in the gunfight at Matewan, West Virginia in 1896."
J.D. Charles writes: "Cap Hatfield, looms large over the entire [Hatfield-McCoy feud]. [He] was often portrayed as a lawless murderer; but the authors [of the book 'The Tale of the Devil'] show him to have been a man who seemed to resent being used as a Lieutenant by his father, and a man who sought peace later in life - first by farming, then by studying to be an attorney, and finally becoming a security guard. One of Cap's last scrapes was a shooting incident on an Election Day that was clearly self defense." Cap is buried in the Cap Hatfield Cemetery in Stirrat, Logan County, West Virginia.
