John Hacker, Son of Julius Hacker and Easter Burns Hacker

I am looking for information on John Hacker, son of Julius Hacker and Easter Burns Hacker. He was born December 8, 1866 and died February 6, 1889 at the age of 22. He was born and died in Clay County Kentucky but no one seems to know anything about him. He was married to Nancy Ann Hensley and had two children: Julius Hacker and Rebecca J. Hacker. He is buried in the Hensley Cemetery in Clay County close to the intersection of Hwy 149 and 66. I would love to find out how he died and exactly where the cemetery is located. The Clay County Courthouse and records prior to 1891 (I believe) were destroyed in a fire, so there is no record that I know of for cause of death. We were in the vicinity of Hwy 149 and 66 in Clay County a few weeks ago, but could not located the cemetery. There are several Hensley Cemeteries in Clay County, but he is buried with Nancy Ann's parents, Henry and Rebecca. ANY information on him would be so much appreciated! He is our Great Grandfather. Thank you!
