Rhiannon means 'great queen' or 'divine queen,' but not 'great goddess.' reflecting the same mythological roots as Rhiannon. 'Rhianon does not share the same rich history as Rhiannon, which is a name deeply rooted in Welsh mythology and associated with the goddess of horses and sovereignty.' Like Rhiannon, it has been influenced by the Victorian revival of Old Welsh names and has seen a slight increase in usage due to its association with the legendary figure.
