History & Origin
Riannon is a Welsh name, an -h-less spelling of Rhiannon that goes back to the Celtic Rigantona, 'great queen.' Rhiannon appears in the Mabinogi as an otherworldly queen on a white horse, and the American spelling Riannon rode the same wave of interest in the later twentieth century.
It was never common in this spelling, given to only about fifteen girls a year even at its peak in the late nineteen-eighties. A girl named Riannon then is in her late thirties today, part of the cohort that grew up with the Fleetwood Mac song.
