11.  Kentucky Atlas & Gazetteer (online at the University of Kentucky; paraphrased by DGM):

Corbin is the largest town in Whitley Co., KY, with a population in 1990 of 7419.  It was founded ca. 1800 and originally named Lynn Camp (later Lynn Camp Station) for William LYNN, an early founder.  When the first post office was opened in 1883, the name was changed to Cummins, in honor of Nelson CUMMINS, another early founder.  Then, in 1885, the name was changed to Corbin, in honor of a local minister, Rev. James Corbin FLOYD.  The town of Corbin was incorporated in 1905.

From what I can gather reading elsewhere, the name was changed to Cummins because there already was a post office named, Lynn.  Then it turned out there already was a post office named Cummins, so they needed a new name.  Someone decided to name it for Rev. James Corbin FLOYD, but it turned out there already was a Kentucky post office named, Floyd, so the name was changed to the Reverend's middle name, not his surname.  Or at least that's the story...  The question remaining for CORBIN researches is:  How did our subject get the middle name, "Corbin"?
