Have you checked with the Gateway Museum Center in Maysville? They have books that cover pretty much every cemetery in Mason and Fleming counties, including old family cemeteries.
There is also a Ringo section in the main Flemingsburg Cemetery. It contains a number of burials that were moved there when the Ringo family cemetery was about to be flooded in the 1970s, but may have been there earlier with other Ringo family members. My 4th-g-grandmother Grace Glasscock (married names Rector, Quaintance), who was Alburtis Ringo's mother-in-law, is buried there.
