What does the name Rion mean?
Rion is a spelling of Ryan, pronounced the same way, so it shares Ryan's meaning and origin.
Ryan is the English form of the Irish surname Ó Riain, earlier Ó Riaghain, 'descendant of Rian'. The meaning of the old personal name Rian is not known: Wikipedia quotes the Irish historian John Ryan's view that it is so ancient its meaning was lost before records began. Popular books often give 'little king' or 'champion', but those glosses are guesses. Ryan is one of the most common surnames in Ireland. As a first name it has been used increasingly for both boys and girls since the 1970s, according to Wikipedia, and Wiktionary notes the re-Gaelicized spelling Rian in modern Ireland.
