Good question! From Boone's wikipedia entry:
Boone died on September 26, 1820, at Nathan Boone's home on Femme Osage Creek. He was buried next to Rebecca, who had died on March 18, 1813. The graves, which were unmarked until the mid-1830s, were near Jemima (Boone) Callaway's home on Tuque Creek, about two miles (3 km) from present day Marthasville, Missouri. In 1845, the Boones' remains were disinterred and reburied in a new cemetery in Frankfort, Kentucky. Resentment in Missouri about the disinterment grew over the years, and a legend arose that Boone's remains never left Missouri. According to this story, Boone's tombstone in Missouri had been inadvertently placed over the wrong grave, but no one had corrected the error. Boone's Missouri relatives, displeased with the Kentuckians who came to exhume Boone, kept quiet about the mistake and allowed the Kentuckians to dig up the wrong remains. There is no contemporary evidence that this actually happened, but in 1983, a forensic anthropologist examined a crude plaster cast of Boone's skull made before the Kentucky reburial and announced that it might be the skull of an African American. Black slaves were also buried at Tuque Creek, so it is possible that the wrong remains were mistakenly removed from the crowded graveyard. Both the Frankfort Cemetery in Kentucky and the Old Bryan Farm graveyard in Missouri claim to have Boone's remains.[26]
