Rhiannan

Meaning & origin

Rhiannan is a modern spelling variant of Rhiannon, a name deeply rooted in Welsh mythology. While Rhiannon itself has enjoyed moderate popularity in the U.S., especially after the 1976 Fleetwood Mac song brought it into the spotlight, Rhiannan remains a much rarer form. First recorded in 1978, it saw its peak usage in 1998, yet it has never cracked the Top 1000. Its trajectory over the past decade has been stable, with very few births per year. The name is almost exclusively given to girls. Its rarity gives it a distinctive feel for parents seeking a name with Celtic resonance without widespread use.

Rhiannan appears to be a modern respelling or variant of the Welsh name Rhiannon. Rhiannon is a figure from Welsh mythology, the daughter of Hefeydd and the wife of Pwyll; her name is often interpreted as 'great queen' or 'divine queen', derived from the Welsh components rhiain 'maiden' and -on, a suffix. The spelling Rhiannan emerged in the late 20th century, likely as a creative alteration. It has seen sporadic use in the United States since 1978, primarily for girls.
